The most common orthopedic disease that can cause hip pain is pear-shaped muscle syndrome, which is mainly caused by inflammatory damage to the pear-shaped muscle due to cold, labor injury or fall, trauma, etc., resulting in swelling of the pear-shaped muscle, squeezing the sciatic nerve and causing hip pain. Severe pear-shaped muscle syndrome patients will have pain in the legs, even limited leg movement, and the symptoms are aggravated when walking, and some patients will not dare to exert force on one leg because of the pain. 2, patients with lumbar disc herniation will also have symptoms of hip pain. Because the sciatic nerve is formed by the combination of the lumbar spinal nerve, once the lumbar spinal nerve is compressed the symptoms of sciatic nerve pain will appear. Patients with a herniated lumbar disc can be aggravated by bending over, or by overwork, and keeping a sitting posture for a long time can also cause the disease to recur.
