Meat arthralgia is a symptom in which the limbs are slow to move and unable to hold their bodies together, even though the patient can eat and drink. From "Suwen·Four Seasons Acupuncture and Countermeasures" it is said: "If the Taiyang meridian is excessive, the disease will be caused by cold in the middle of the body." It is caused by improper diet and rich food that damages the spleen. The spleen governs the muscles. If the spleen is weak, the flesh will not be nourished. If the flesh is not nourished, the skin will not be smooth. If the skin is not smooth, the pores will be loose, and the evil wind, cold, heat and dampness will easily enter. If it is not treated for a long time, it will cause meat arthralgia. The symptoms are that the patient can eat but cannot feel full and happy, and the limbs are weak and cannot hold their bodies together. It is advisable to control diet to regulate the internal organs, and to have a regular daily life to calm the spleen, and then follow the meridians to supplement and purge to seek recovery."
