Posterior thigh muscle strain

　　The etiology of this disease includes the following two situations:

　　1. Fall and sprain:Due to trauma caused by violence or indirect violence, excessive abduction of the thigh, injury to the meridians and collaterals, and poor circulation of Qi and blood, Qi and blood stasis, phlegm blocking the meridians and collaterals, 'blockage leads to pain'.

　　2. External invasion of pathogenic factors:Due to fatigue and sweating, attacked by cold and damp pathogenic factors. The Qi and blood in the human meridians circulate throughout the body in a continuous cycle. When cold pathogenic factors invade the meridians, they congeal and contract, causing blockage of the meridians and collaterals, and retention of the blood, leading to stagnation and poor circulation.

　　Patients with this disease, due to local blood and Qi circulation disorders caused by injury to the meridians and collaterals, Qi stagnation and blood stasis, blockage of the meridians and collaterals, 'blockage leads to pain', can lead to the hip and knee joints being slightly flexed and externally rotated. Due to increased pain during the movement of adduction and abduction of the thigh, due to pain, it can lead to limping when walking. Pain in the hip joint makes it difficult to bear weight while walking, the knee joint of the affected limb is slightly flexed, and the foot is gently landed on the tip of the foot, and then the weight-bearing limb is changed quickly, with a short and unstable gait, which is seen in hip tuberculosis, transient synovitis, aseptic necrosis of the femoral head, and other conditions.

　　The strain of the posterior thigh muscle is usually manifested as pain in the posterior side of the thigh during sudden and severe muscle contraction (such as when a sprinter is blocked at the starting line or a high jumper jumps from a depression), with tenderness on the posterior side of the thigh, but it will not extend below the knee joint. Sciatica usually has no tenderness and extends below the knee. Deep pain in the thigh may also be due to fatigue fracture of the femur, and diagnosis depends on bone scanning.

　　In terms of prevention, it is mainly to pay attention to the care of patients to prevent complications from occurring.

　　1. The patient lies on his back, and the pad of the thumb of the same side is pressed on the affected area for 1-2 minutes to the degree of feeling sore and comfortable.

　　2. While the patient is in the same position, use the pad of the thumb of the same side or the opposite side to rub the painful area of the adductor cavity 8-10 times to the degree of slight pain locally.

　　During the physical examination of patients with this disease, swelling can be seen on the inner side of the thigh. There is marked tenderness. When the hip joint is passively abducted, there is marked pain. Special examinations can find a positive resisted test of the adductor muscle, a positive '4' test. The '4' test is also known as the Gaenslen test, which is mainly used for the diagnosis of lumbar sacral joint disease, sciatica, and ankylosing spondylitis, etc.

　　1. What foods are good for the body for posterior muscle strain of the thigh

　　It is advisable to eat light, eat more vegetables and fruits, rationally match the diet, and pay attention to adequate nutrition. It is necessary to increase nutrition, eat more protein-rich foods such as fish, eggs, and soy products, and appropriately increase calcium. Drink more water, eat more vegetables and fruits, such as green vegetables, celery, bananas, etc.

　　2. What foods should be avoided as much as possible

　　Avoid spicy foods: such as chili, mustard, etc. Smoking and drinking should be avoided.

　　The treatment of this disease is mainly symptomatic treatment, RICE is helpful for acute injury. Other treatments include comfort, (at present, there are two types of commonly used placebos: one is drugs without specific therapeutic effects, such as glucose, lactose, normal saline, etc.; the other is drugs with certain therapeutic effects but unrelated to the disease being treated, such as vitamin drugs, calcium gluconate, licorice tincture, ammonia water, and unrelated Chinese herbal decoctions, etc. Although placebos themselves are some drugs without specific therapeutic effects or unrelated to the disease being treated) stop running and jumping, and strengthen the gluteus maximus exercises after recovery, etc.
