Many patients who come to my clinic often ask me the same question: "Doctor, my thigh twitches and my eyelid twitches too—these two areas are so far apart, why do they torment me at the same time?" Some worry it's a precursor to a stroke, others fear it's a neurological problem, and some simply think it's due to "lack of rest" and that it will pass if they just wait. From the perspective of traditional Chinese medicine (TCM) clinical practice, this combination is actually not uncommon, and it often points to a core pair of organ relationships—the Liver and the Spleen.
To understand this problem, we must first move beyond the surface phenomenon of "muscle twitching." The ancients never understood the body by cutting it into anatomical sections; rather, they observed it through the flow of qi and blood. The inner thigh is the pathway through which the Liver meridian and Spleen meridian pass. In TCM, the eyelid is called the "muscular wheel" (rou lun), and it is precisely governed by the Spleen. One meridian and one wheel both fall within the jurisdiction of the Liver and Spleen organs: the Liver governs the sinews, and the Spleen governs the muscles. Abnormal twitching of sinews and muscles is like the two organs sending you a signal.
I. Liver Blood Deficiency and Spleen Transport Failure: Two Fruits on the Same Vine
Eyelid twitching may seem trivial compared to thigh cramps, but upon careful questioning, these patients often share a common trait: excessive mental strain during the day, prolonged eye use, and irregular eating habits. Mental strain harms the Spleen; prolonged visual focus harms the blood. When the Spleen is deficient, the source of qi and blood production is weakened, and the Liver's function of storing blood loses its material foundation. When liver blood is insufficient, the sinews and vessels lose their nourishment—much like ropes on a dried riverbed that sway at the slightest breeze. Manifested in the body, this takes the form of various spasms and twitches.
"The Liver receives blood and thus can see; the feet receive blood and thus can walk; the palms receive blood and thus can grasp; the fingers receive blood and thus can hold." —《Yellow Emperor's Inner Classic: Plain Questions, Chapter 10: Formation of the Five Organs》
This passage vividly describes how one and the same blood simultaneously nourishes the eyes and the limbs. Liver blood functions like the body's irrigation system: the eyes rely on it to see clearly, and the legs rely on it to move. When blood is insufficient, the body prioritizes core organs such as the heart and brain, while the extremities and the area around the eyes—those "remote regions"—are prone to the "drought" of insufficient blood supply, manifesting as twitching or spasming.
Here's the question: if it's liver blood deficiency, wouldn't simply supplementing blood solve the problem? Clinically, it's not that simple. For many people who supplement more aggressively and twitch even more violently, the problem lies precisely in the Spleen's transport function. The Spleen is responsible for transforming food into qi and blood. If spleen qi is weak, the nourishing substances taken in not only fail to become blood but instead cause stagnation in the middle jiao, generating dampness and phlegm, further obstructing the delivery of qi and blood to the extremities.
"When drink enters the stomach, the essential qi overflows and is transported upward to the Spleen. The Spleen disperses the essence and sends it upward to the Lungs. The Lungs regulate the waterways and send it downward to the Bladder." —《Yellow Emperor's Inner Classic: Plain Questions, Chapter 21: Treatise on the Differentiating of the Meridians》
This classical passage reveals the body's pivotal mechanism: the Spleen "disperses essence" from water and grain to the entire body. If the Spleen's function becomes sluggish, the essential substances cannot be properly distributed, leaving the thigh sinews and eyelid muscles in a state of "supply interruption." The clinically common simultaneous twitching of the thigh and eyelid represents a pattern of "liver blood deficiency as the root, and spleen transport failure as the manifestation." Treatment requires not only nourishing liver blood but also restoring the Spleen's distributing function—both are indispensable.
So how can one tell whether one leans more toward liver blood deficiency or toward spleen deficiency with dampness retention? This requires returning to the body's sensations. Those with relatively greater liver blood deficiency often experience dry eyes, astringent eyes, brittle nails, and easy numbness in the calves. Those with spleen deficiency and dampness tend to experience drowsiness after meals, sticky stools, twitching that shifts location, and can even feel a "small blister" sensation under the skin. These are two different emphases, and the treatment strategies naturally differ—but even this distinction remains only a broad directional guide.
This then leads to an even deeper question: why does liver blood deficiency with spleen transport failure specifically manifest as spasms rather than pain or numbness? In classical theory, spasms fall under the category of "wind," which shifts the topic to another dimension of thinking.
II. Blood Deficiency Generating Wind and Wood Overwhelming Earth: Where Does the "Wind" Behind Spasms Come From?
The "wind" in TCM is divided into external wind and internal wind. Simultaneous spasms of the thigh and eyelid mostly belong to internal wind, the root cause being blood deficiency. Blood is a yin substance. When yin blood becomes deficient to a certain degree and can no longer restrain the body's yang qi, the yang qi runs wild like a runaway horse, darting through the sinews and vessels. This darting motion, when manifested in the muscles, appears as twitching and spasming.
"All wind conditions marked by dizziness and shaking belong to the Liver." —《Yellow Emperor's Inner Classic: Plain Questions, Chapter 74: Treatise on the Most Important Principles》
The character "diao" (Drop) means tremor and twitching. In just seven characters, the ancients pinpointed the core attribution of this type of problem. The Liver is the organ of wind and wood, housing ministerial fire within. When the Liver's substance loses the nourishment of yin blood, internal wind is generated. Wind is characterized by movement, hence the wandering, intermittent nature of the twitching. Although the thigh and the eyelid are different locations, in the face of liver wind, they are two trees in the same forest shaken by the same breeze.
But this is not the whole picture. Remember the Spleen mentioned earlier. In the Five Elements system, the Liver and Spleen relate as Wood and Earth. Under normal circumstances, Wood can "dredge" Earth, helping the Spleen and Stomach with transformation and transport. If liver qi becomes excessive, it can instead "overwhelm" spleen earth—this is known as "Wood overacting on Earth." With regard to spasms, a vicious cycle is commonly seen: liver blood deficiency → internal liver wind stirring → transverse invasion insulting the Spleen → weaker spleen transport → even less qi and blood production → even more severe liver blood deficiency. In this way, the body is drawn into an ever-consuming spiral.
Clinically, simultaneous spasms of the thigh and eye are most commonly seen in individuals who work long hours at a desk, overuse their eyes, and lack physical activity. Such people often also tend toward emotional tension or anxiety. Emotional tension exacerbates liver qi stagnation; prolonged stagnation transforms into fire; fire further consumes yin blood; the less yin blood there is, the more wind stirs, and the more frequent the twitching becomes. In terms of disease location, the Liver governs the sinews, the Spleen governs the muscles, the eyelid belongs to the Spleen, and the inner thigh is governed by the Liver meridian. In terms of disease nature, it is mostly a pattern of root deficiency with branch excess—deficiency in blood and qi, excess in wind and stagnation.
So, in the face of this state of "wind stirring," is there any daily care that can be done? From a TCM dietary perspective, one may pay attention to ingredients that help nourish blood and soften the Liver, such as goji berries, mulberries, and spinach, while also incorporating spleen-strengthening ingredients like Chinese yam, lotus seeds, and millet. It must be emphasized that these ingredients differ in their properties and should be consumed in moderation according to one's individual constitution; for specific combinations, please consult a licensed TCM practitioner. Regarding daily routine, attention should be paid to the quality of nighttime sleep. The zi hour (11 PM to 1 AM) is the period when the Gallbladder meridian is in command and blood returns to the Liver. People who stay up late for extended periods often have impaired pathways for qi and blood to return, leading to more frequent spasms.
TCM theory also indicates that emotional regulation occupies a key position in both prevention and nurture. The Liver "is associated with anger in the emotions," and the Spleen "is associated with overthinking." Excessive anger harms the Liver, and excessive rumination harms the Spleen. For spasm-type problems, practicing "letting go" is more important than "controlling." When the body twitches, there is no need to become overly anxious—the more attention and worry one gives it, the stronger the liver wind tends to become, and the more frequently it twitches. This is like holding a small bird in your hand: the tighter you grip, the more it struggles.
In terms of exercise and guidance, gentle exercises such as tai chi and baduanjin (Eight Pieces of Brocade) can promote the movement of qi and blood. However, it should be noted that the intensity and type of exercise should be determined by a licensed TCM practitioner based on individual constitution. Walking is a relatively safe option; the key lies in the rhythm of "a hundred steps after a meal"—there is no need to pursue profuse sweating; slight perspiration is sufficient. Sweat is the fluid of the Heart, and excessive sweating can further deplete yin blood.
Clinically, if some individuals also present with dizziness, tinnitus, bitter taste in the mouth, dry throat, irritability, and a tendency to anger, the condition may belong to the pattern of liver yang hyperactivity and internal liver wind stirring. In such cases, simple supplementation is not appropriate, and it is even less suitable to self-administer warming and drying agents. Another subset of people may experience localized soreness, swelling, and heaviness after spasms—this is often related to dampness obstruction, and the treatment approach needs to address both resolving dampness and nourishing blood, which differs from simple liver blood deficiency. Clearly, even with the same manifestation of thigh and eye spasms, the underlying patterns can be quite different—this is precisely the embodiment of TCM's principle of "treating the same disease with different methods."
"In treating disease, one must seek the root." —《Yellow Emperor's Inner Classic: Plain Questions, Chapter 5: The Great Treatise on the Correspondence of Yin and Yang》
The "root" being sought does not lie in the surface symptoms, but in the fullness or emptiness of qi and blood, the coordination of the organs, the free flow of emotions, and the rhythm of daily rest. The process of seeking the root is not a simple one-to-one correspondence between a formula and a point, but rather a re-comprehension and re-adjustment of the body's overall state.
The next time your thigh or eyelid twitches, take a moment to notice: does it occur after prolonged sitting or eye use, or does it worsen after emotional fluctuations? Does it twitch a few times and then stop, or does it persist continuously? Is the position fixed or wandering? Is it accompanied by a feeling of dryness or a feeling of heaviness? These details are the most subtle pieces of evidence in TCM clinical pattern differentiation, and they are the first "self-observation record" you can provide for your body.
Have you ever considered that the simultaneous spasm of your thigh and eyelid might not just be an incidental reaction of localized muscles? It may be your body reminding you: blood has already run short in certain corners, and wind is already flowing quietly through your meridians. Rather than fighting the surface twitching, perhaps it is wiser to listen to this whisper from your body and re-establish the order of life from the very source—nourishing liver blood, strengthening spleen transport, and harmonizing emotions.

Related Knowledge Q&A
1. What causes liver blood deficiency and spleen transport failure?
In TCM, the assessment of liver blood deficiency and spleen transport failure must be approached from a holistic pattern differentiation perspective, using the four diagnostic methods (inspection, auscultation-olfaction, inquiry, and palpation) combined with individual constitutional characteristics for comprehensive judgment—it cannot be generalized. The specific treatment direction should be determined by a licensed TCM practitioner after an in-person consultation.
2. How long is the treatment cycle for blood deficiency generating wind and wood overacting on earth?
The treatment cycle varies from person to person and is related to factors such as one's constitutional foundation and compliance with lifestyle adjustments. TCM emphasizes gradual progress. The specific duration must be assessed by a licensed TCM practitioner after an in-person consultation based on individual circumstances; this material does not provide a specific cycle commitment.
What should be noted in daily life during TCM treatment?
For daily care, it is recommended to maintain a regular sleep schedule, a balanced diet, moderate exercise, and emotional stability. Specific precautions should be flexibly adjusted according to individual constitution and seasonal changes. Consult a licensed TCM practitioner for targeted advice.
