Right hip pain may be related to trauma, ischemic necrosis of the femoral head, pudendal nerve entrapment, lumbar disc herniation, pyriformis syndrome and other diseases. 1. Trauma: If the right hip lands on the ground, it may cause the right side of the neck of the bone, the femoral roughness fracture, especially the elderly are more prone to fracture. The fracture will cause severe pain in the right hip, and at the same time, the right thigh will show flexion, inward retraction, shortening deformity, unable to stand and walk. 2. Femoral head necrosis: Ischemic necrosis of the right femoral head can also cause pain in the right hip. The pain increases continuously with the development of the disease, and is usually relieved after resting and aggravated after activity or weight-bearing. 3. Superior gluteal nerve entrapment: Superior gluteal nerve entrapment can also cause pain in the right buttock, which is caused by nerve compression due to nerve outlet lesion, and the pain usually does not exceed the knee joint. 4. Herniated lumbar disc: Herniated lumbar disc compresses the nerve that innervates the right buttock, and the nerve will function abnormally after compression, which will also cause pain, and the pain will radiate to the thigh and calf in severe cases. 5. Pear-shaped muscle syndrome: pear-shaped muscle syndrome can also cause right hip pain, is due to the pear-shaped muscle injury, inflammation, edema, spasm, etc., stimulation of the sciatic nerve caused by the general right lower extremity to do the pain aggravated by internal rotation, abduction and external rotation to reduce. There are many reasons for the right hip pain, we suggest that patients go to the hospital for medical examination, after clarifying the cause of the disease for targeted treatment.
