Aching and Twitching in Both Bones and Eyelids: Two Seemingly Unrelated Disturbances, One Shared Origin?

In the outpatient clinic, a woman in her late forties sat down and spoke rapidly: "Recently, I've been feeling a sour ache deep in my bones, as if wind were seeping in, with a throbbing pain. My eyelid has joined in too—my left eyelid has been twitching for nearly half a month, and it's driving me restless." She paused, then asked hesitantly, "The bones and the eyelid—what do they have to do with each other? Why would they act up together?"

In Chinese medicine clinical practice, this question is actually not uncommon. What it tests is precisely one of the most central propositions in Chinese medical thinking: is the human body an interconnected whole, or an assembly of independent parts? The textbook answer is holism, but the clinical challenge lies in this—when symptoms manifest in two completely unrelated locations, how does the practitioner find the common pathway from seemingly chaotic clues? If eyelid twitching were merely a local muscle problem, why would the bones simultaneously feel uncomfortable? Conversely, if the bone problem originates from deeper levels, what role does the superficial manifestation at the eyelid play? Without clarifying this layer, it is all too easy to fall into the error of "treating the head when the head hurts."

Clinically, simultaneous throbbing pain in the bones and eyelids is most commonly seen in people with depletion of liver-kidney yin and blood, with internal stirring of deficiency wind. Why the liver and kidneys? Here we must first clarify an easily overlooked fact about the channels.

I. Bones and Eyes Are Not Separate Paths at the Channel Level

The *Huangdi Neijing·Suwen*, Chapter 5, "Yinyang Yingxiang Dalun," contains a passage: "The kidneys generate bone marrow; the marrow generates the liver; the liver generates the sinews; the sinews generate the heart; the liver governs the eyes." The common reading of this passage is the sequence of five-phase generation among the viscera, but clinically, the three characters " Marrow generates the liver" (the marrow generates the liver) deserve deeper reflection. Bone marrow nourishes the liver-wood; liver blood flows upward to nourish the eyes—between bone and eye lies a bridge of transformation through marrow and blood. If kidney essence is insufficient, the sea of marrow is depleted, and liver blood has no source from which to be transformed. When liver blood is depleted, the eyes lose nourishment, and the eyelid muscles become the first site to raise the alarm.

But pattern differentiation in Chinese medicine cannot stop here. If there is only eyelid twitching, it may simply be local disharmony of qi and blood; if accompanied by "throbbing bone pain," one must look beyond qi and blood to consider the interaction of yang qi and yin fluids. Pain within the bones is generally treated from the kidneys in Chinese medicine. The *Suwen·Xuanming Wuqi Pian* states that "the kidneys govern the bones," and the nature of the pain is "throbbing"—with a wave-like quality, coming and going, like a pulse—and this already carries the image of wind.

Where does the wind come from? One type is wind generated by blood deficiency: the liver stores blood; when blood is insufficient, the sinews lose nourishment, become empty and ungoverned, and wind arises internally. Another type is yang hyperactivity due to yin deficiency: kidney yin fails to restrain yang, yang qi floats upward, transforms into wind, and disturbs the upper body. Both types of wind are rooted in the liver and kidneys, but the mechanisms differ slightly.

| Pattern Differentiation | Main Manifestations | Accompanying Symptoms | Tongue and Pulse Features | Pathomechanism |

|---------|---------|---------|---------|---------|

| Blood deficiency generating wind | Sour throbbing pain in bones, mild pain intensity, eyelid twitching with weak sensation | Pale complexion, dizziness and blurred vision, numbness of limbs, pale nails | Pale tongue, thin white coating, thin and weak pulse | Liver blood insufficiency, sinews losing nourishment, internal stirring of deficiency wind |

| Yin deficiency with yang hyperactivity | Throbbing bone pain with soreness and distension, high-frequency eyelid twitching | Tinnitus, soreness and weakness of lower back and knees, five-center heat, dry mouth and throat | Reddish tongue, scant or peeled coating, thin and rapid pulse | Kidney yin depletion, water failing to nourish wood, yang hyperactivity with wind stirring |

| Cold congealing in bone joints with concurrent blood deficiency | Bone pain preferring warmth and disliking cold, throbbing pain varying in severity, eyelid twitching aggravated by cold | Cold extremities, mental fatigue, faint eyelid twitching | Pale dark tongue, white slippery coating, deep tight or wiry tight pulse | Yang qi insufficiency, cold congealing in channels, blood deficiency with wind taking advantage |

In blood deficiency generating wind, the disease location is the liver, the nature is deficiency, and the course is relatively slow—like a lamp with little oil, the flame flickering dim and bright by turns. In yin deficiency with yang hyperactivity, the disease location is the liver and kidneys, the nature is a mix of deficiency and excess, and the course is somewhat more urgent—like water boiling dry in a pot, bubbling and churning. There is yet another condition: cold congealing in bone joints with concurrent blood deficiency. These people typically have a distinct preference for warmth and pressure at the site of throbbing bone pain, eyelid twitching that is especially noticeable after exposure to cold, a pale dark tongue with a white slippery coating, and a deep tight pulse. This is a condition where yang deficiency fails to warm and nourish, cold evil takes advantage of the deficiency to enter, blood vessels congeal and stagnate, and deficiency wind moves in combination with cold evil. The treatment directions for the three conditions are quite different. If one simply classifies all cases of throbbing pain in both bones and eyelids as wind-heat, it is easy to make clinical errors.

This also brings out a key branch point in clinical pattern differentiation—if the throbbing pain worsens with cold and is relieved by warmth, then it may lean toward yang qi deficiency with cold congealing in the sinews, rather than simple yin-blood depletion. The distinction between the two is quite clear on tongue and pulse: yin-blood depletion shows a red tongue with scant coating and a thin rapid pulse; yang deficiency with cold congealing shows a pale dark tongue with a white slippery coating and a deep tight pulse. If one fails to differentiate and mistakenly uses cold, cooling, yin-nourishing medicinals, it will further damage yang qi and aggravate the throbbing bone pain.

1. The Liver Governs the Sinews and Opens to the Eyes—The Traditional Pathomechanism Framework for Eyelid Twitching

In Chinese medicine's classical understanding of eyelid twitching, the classic description points to "sinew twitching and flesh jumping" (jinti roushun). *Shanghan Lun*, entry 82, mentions "the body twitching and trembling as if about to fall"—although it refers to whole-body muscle twitching, the eyelid, as one of the thinnest muscle groups on the face, is often the first place where sinew twitching and flesh jumping manifest. Clinically, one cannot assume that eyelid twitching is merely "left eye twitches for wealth, right eye twitches for disaster"—that is folklore, with no bearing on medical principle.

From the channel pathways, the Foot-Taiyang Bladder Channel "originates at the inner canthus," the Foot-Yangming Stomach Channel's "Chengqi" point lies below the eye, and the Hand-Shaoyang Sanjiao Channel's "Sizhukong" point is at the lateral eyebrow. The eyelid region is traversed, directly or indirectly, by at least six channels. But the key to clinical differentiation is not counting channels; rather, it lies in judging the difference in attribution between "upper eyelid twitching" and "lower eyelid twitching." The upper eyelid belongs to the Foot-Taiyang Bladder Channel's region, and the lower eyelid to the Foot-Yangming Stomach Channel's territory—this channel-based regional division has clinical reference value. Upper eyelid twitching accompanied by occipital headache and stiffness of the neck and back is mostly in the Taiyang channel sinews; lower eyelid twitching accompanied by epigastric and abdominal distension and irregular bowel movements is mostly in the Yangming channel sinews. If throbbing bone pain appears simultaneously, one must determine whether the Taiyang channel has been attacked by cold, or the Yangming channel sinews have lost nourishment, or whether liver-kidney depletion is affecting all channels.

However, eyelid muscle twitching can also be related to the spleen and stomach. "The spleen governs the muscles." If spleen-stomach qi is deficient, the muscles lose their nourishment, and eyelid twitching may occur, accompanied by fatigue and weakness of the limbs. In this case, throbbing bone pain may not necessarily be a kidney problem, but rather water-dampness overflowing and channel qi failing to move smoothly. Therefore, when encountering simultaneous twitching in bones and eyelids clinically, one should first ask one question: is the twitching sensation "throbbing with a pounding quality" or "fine and trembling"? The former leans toward wind-yang disturbing upward; the latter leans toward qi-blood insufficiency. A single detail's difference can send the pattern differentiation in entirely different directions.

The fine trembling kind of twitching, like a small bird pecking at food, is small in amplitude but rapid in frequency, and is most commonly seen in qi-blood deficiency with muscle malnutrition. If accompanied by a sallow complexion, mental fatigue, a pale tongue, and a weak pulse, the treatment principle focuses on supplementing qi, nourishing blood, and warming the sinews. The pounding kind of twitching has a more obvious amplitude and a sense of impact, typically seen in liver-yang transforming into wind or yin deficiency with yang hyperactivity. If accompanied by headache, dizziness, irritability and easy anger, the treatment principle requires calming the liver, subduing yang, nourishing yin, and extinguishing wind. To summarize in one sentence: twitching is a wind manifestation, but the deficiency or excess, cold or heat, interior or exterior nature of the wind must be identified through careful attention to detail.

2. The Kidneys Govern the Bones and Generate Marrow—Another Layer of Meaning in Throbbing Bone Pain

Bones themselves have no pain receptors. What Chinese medicine calls "bone pain" actually refers to discomfort in the "bone joints" or "periosteal attachment sites." Throbbing pain implies a wave-like rhythm to the pain, and this rhythmic quality in Chinese medical theory is often associated with "wind."

The kidneys store essence; essence generates marrow; marrow nourishes the bones. When kidney essence is sufficient, the bones are strong and solid; when kidney essence is depleted, the marrow loses its source of supplementation, a feeling of emptiness arises in the bone joints, and external pathogens or internal wind can easily take advantage of the deficiency and enter. Throbbing bone pain accompanied by soreness and weakness of the lower back and knees, frequent nocturia, and tinnitus like the chirping of cicadas belongs to kidney essence depletion with insufficiency of the sea of marrow, where deficiency wind wanders between the bones. In this case, the "throbbing" is not muscle twitching but a deep, emptiness-like pulsation within the bone joints—similar to the sensation of "wind within the bones."

But the reverse situation also deserves attention: if throbbing bone pain is accompanied by local redness, swelling, heat, and pain that worsens with heat, it may belong to damp-heat pouring downward or heat toxin accumulating and binding in the bone joints. In such cases, the approach of clearing heat and promoting diuresis is needed. Clinically, this is commonly seen in bone and joint pain due to damp-heat obstruction (bi syndrome). Yin-blood deficiency and damp-heat often intermingle, making differentiation difficult. In such a case, mistakenly using the method of supplementing the liver and kidneys would actually aggravate the dampness evil. When encountering throbbing pain in both bones and eyelids, asking one further question about whether the pain changes with heat or cold, and whether there is any local burning sensation, can help distinguish cold from heat, deficiency from excess. Damp-heat-induced throbbing pain is most commonly seen in the bone joints of the lower limbs, accompanied by oily facial skin, a bitter taste and greasy sensation in the mouth, yellow urine, a red tongue with a yellow greasy coating, and a slippery rapid pulse. Yin-blood deficiency throbbing pain, by contrast, is accompanied by emaciation, night sweats, dryness of the mouth and throat, a red tongue with scant coating, and a thin rapid pulse. One is excess, the other deficiency—they must not be confused.

II. Following the Nature of Foods and Medicinals, Seeking a Gentle Path of Nourishment and Care

Once the mechanism is understood, looking at foods and medicinals becomes much clearer. The core of throbbing pain in both bones and eyelids is the fundamental picture of "liver-kidney yin and blood insufficiency with internal stirring of deficiency wind." The direction of care therefore revolves around supplementing the liver and kidneys, nourishing blood and relaxing the sinews, and calming internal wind.

1. Mulberry (Sangshen): A Seasonal Fruit That Nourishes Liver-Kidney Yin

Mulberry was recorded in the *Xinxiu Bencao* as "eaten alone, it governs wasting-thirst." Later physicians generally classified it among medicinals that supplement the liver and benefit the kidneys. Its flavor is sweet, its nature is cold, and it enters the heart, liver, and kidney channels. It can nourish yin and blood, generate fluids, and moisten dryness. For the woman mentioned earlier—if her tongue is on the red side with scant coating, her pulse is thin and rapid, and she also has soreness and weakness of the lower back and knees and dry mouth and throat—then mulberry as a daily food is a very well-matched choice.

Its scope of application should be anchored to the target of "yin-blood insufficiency." When yin and blood are sufficient, the sinews are nourished, and the "deficiency wind" of eyelid twitching is counterbalanced. For people with fine twitching of the eyelids and soreness of the bones and joints, mulberry's nature is gentle and lasting. However, its nature is somewhat cold, so people who usually have spleen-stomach deficiency cold and are prone to diarrhea should be cautious and avoid using large amounts.

2. Black Sesame (Heizhima): A Gentle Substance That Replenishes Essence and Blood

Compared with mulberry's cold moistness, black sesame has a much more balanced character. Its flavor is sweet, its nature is neutral, and it enters the liver, kidney, and large intestine channels. Its functions are to supplement the liver and kidneys, benefit essence and blood, and moisten the intestines to relieve dryness. What is most commendable about black sesame is its "moistening things silently" power of supplementation—it is not as cloying as donkey-hide gelatin (Ejiao), nor as warm and drying as deer antler. It is suitable for long-term use as a food for gradual nourishment.

For the deeper issue behind throbbing bone pain—kidney essence depletion and insufficiency of the sea of marrow—black sesame's supplementing direction points directly at kidney essence. Essence generates marrow; when marrow is sufficient, the bones are strong. "Strengthening the bones" is not the same as "stopping pain," but it does provide some help in improving sore, aching throbbing pain in the bones and joints. Clinically, such people often also have premature greying of the hair and dry stools—black sesame addresses all three manifestations at once.

If mulberry is likened to a fine stream moistening things gently, then black sesame is more like a slow-melting slab of fat and paste. The directions of the two do not conflict, but their emphases differ. Mulberry leans toward nourishing yin and clearing heat, suitable for those with yin-blood deficiency accompanied by signs of deficiency heat; black sesame leans toward replenishing essence and enriching blood, suitable for those with essence-blood depletion without obvious heat or cold manifestations. If both appear together in the daily diet, mulberry provides the supplement of fluids, and black sesame is responsible for the replenishment of essence and marrow. One moistens, the other fills—when well matched, this can be considered a combination approach worthy of individualized exploration. But it must be emphasized here: specific usage and dosage should be determined by a licensed Chinese medicine practitioner according to individual constitution.

3. Goji Berry (Gouqizi): A Bridge Between Supplementing Yin and Yang in a Balanced Way

Compared with mulberry and black sesame, goji berry plays a role more like a bridge in the topic of throbbing bone and eyelid pain. Its flavor is sweet, its nature is neutral, and it enters the liver and kidney channels. It can both nourish liver-kidney yin and benefit essence and brighten the eyes. For eye-system problems such as eyelid twitching, goji berry is a relatively well-matched food; for osteoporosis or bone joints lacking nourishment, its function of supplementing kidney essence also applies.

Goji berry's most unique value lies in "supplementing both yin and yang in a balanced way." When a person manifests dual deficiency of yin and yang—fear of cold and chills alongside five-center heat—goji berry is neither as warm and drying as cinnamon twigs and aconite, nor as cold as raw rehmannia. Its balanced nature makes it a relatively safe choice for daily dietary therapy. In the context of throbbing pain in bones and eyelids, goji berry can serve as a bridge addressing both the liver and kidneys, and it is also quite flexible when combined with other foods.

4. The Wisdom of Combination: Pairing Two by Two, Each Finding Its Place

Mulberry with black sesame, goji berry with mulberry, black sesame with goji berry—these three pairings each have their own emphasis. Mulberry paired with black sesame combines yin nourishment with essence supplementation, suitable for those with kidney essence depletion complicated by deficiency heat. Goji berry paired with mulberry emphasizes both nourishing liver blood and enriching kidney yin, suitable for throbbing eyelid pain primarily due to liver blood insufficiency. Black sesame paired with goji berry supplements liver-kidney essence and blood in a balanced way, suitable for sore and throbbing sinews and bones without obvious heat manifestations.

Traditional Chinese medicine holds that the compatibility of foods is like human interaction: only those with compatible natures can travel far together. When mulberry's cold yin meets black sesame's warm moistness, the two happen to check each other. Goji berry's balanced nature can buffer mulberry's coldness, and it can also enhance black sesame's efficacy. In the simple combination of two food ingredients, one can see the compatibility wisdom of "different types acting as mutual envoys" (yilei xiangshi) in Chinese medicine.

Of course—dietary care is only one form of maintenance. If throbbing pain in the bones and eyelids persists or gradually worsens, one should consult a formal medical institution, and a licensed Chinese medicine practitioner should conduct a detailed pattern differentiation to determine a specific care plan. The role of foods is to provide sustained nutritional support along the long road of constitution improvement, not to replace medical intervention.

5. Emotions and Daily Routine: Auxiliary Dimensions That Cannot Be Overlooked

From clinical observation, among those with throbbing pain in both bones and eyelids, a considerable number also have poor sleep quality with excessive dreaming and easy waking. "The liver stores blood; when a person lies down, blood returns to the liver." Sleep is the most important period for liver blood recovery. If one stays up late chronically or sleeps lightly and briefly, even the most careful dietary therapy will fail to effectively replenish liver blood.

From the perspective of emotional regulation, the liver's emotion is anger. Suppressed anger injures the liver; liver qi depression transforms into fire and generates wind, which can also manifest as throbbing pain. There is an easily overlooked connection here: if the onset of throbbing pain clearly coincides in time with emotional fluctuations—for example, worsening after anger and easing when the mood is pleasant—then the source of the "wind" is closely related to emotions, and the focus of care should shift to soothing the liver and relieving depression rather than one-sided supplementation.

It should also be noted that throbbing pain in the bones and eyelids may also improve through movement and daoyin exercises. Traditional daoyin techniques emphasize "using intention to guide qi," guiding qi and blood movement through gentle stretching of the limbs, which can help soften the sinews. However, specific practice methods should be carried out under professional guidance; one should not imitate them on one's own, and it is even less advisable to forcibly exercise during acute throbbing pain episodes.

6. A Group Easily Misjudged

Clinically, there is another group of people in whom the mechanism of throbbing pain in the bones and eyelids is entirely different. They often appear haggard and mentally exhausted, having been under high-pressure working conditions for a long time, with irregular diets and scant menstrual volume. For these people, the throbbing pain is not simple yin deficiency, but qi-blood deficiency that has reached a considerable degree—the body is in a state of "overdraft."

What this group shares in common is that the throbbing pain is clearly relieved after rest and aggravated by fatigue. Observing the following—does the eyelid twitching worsen toward evening? Does the sour bone ache appear after physical exertion?—can help assess the degree of qi-blood depletion. At this point, food choices should lean toward sweet and warm qi-supplementing items such as longan meat and red dates, paired with black sesame, addressing both the mutual generation of qi and blood and of essence and blood.

This is an important clinical reminder: when seeing "throbbing pain in both bones and eyelids," one must not be blinded by the single lens of liver-kidney yin deficiency. Qi-blood deficiency and liver-kidney insufficiency can coexist, and they can also occur independently. The distinguishing point lies in the degree of correlation between fatigue and throbbing pain—if symptoms are clearly reduced after rest, the target of depletion shifts from "yin blood" to "qi-blood."

So then, if you were that woman in the consultation room, which clues from your body should you observe? Does the pain worsen with cold or ease with warmth? Is the tongue body reddish with scant coating, or pale dark with a slippery moist coating? Is sleep difficult to initiate or easily interrupted by waking? Are stools on the dry side or loose? These subtle differences are the focal points for the practitioner's differentiation, and they are also guides for you to understand your own condition—after all, the deepest messages of the body are always conveyed through the subtlest signs. Have you ever considered that simultaneous throbbing pain in bones and eyelids might not be two unrelated accidents, but rather the body telling you, in the same language, about a shared origin? Listening to it matters more than masking it.
