Common causes of hip pain in patients include gluteal fasciitis, pear-shaped muscle syndrome, and lumbar disc herniation, as follows: first, gluteal fasciitis: gluteal fasciitis, which is the white fascia on the surface of the gluteal muscles, occurs as a sterile inflammation, and hip pain can occur, characterized by widespread pain and diffuse pressure pain in the hip. The second, pear-shaped muscle syndrome: the pear-shaped muscle is in the area of the ring jump point. If the pear-shaped muscle is inflamed, edematous, or injured, pain will appear in the area of the ring jump point, and when the lower limb is abducted and rotated, the pain is aggravated by doing a positive straight leg raise test and a negative strengthening test, and the pain is aggravated by pressing on the ring jump point. Thirdly, lumbar disc herniation: after the lumbar disc herniation compresses the lumbar 5 nerve and sacral 1 nerve, the pain will radiate from the lumbar region along the hip to the lower limbs, characterized by pain in the lumbar and hip regions at the same time, and a few patients have hip and leg pain, or just hip pain, and a lumbar disc CT can make a clear diagnosis.
