Frequent pain in the depression next to the hip bone can be related to hip joint pathology, trochanteric bursitis, and trauma. Hip joint lesions such as hip joint effusion and ischemic necrosis of the femoral head can cause pain on the outside of the hip. Bursitis is an aseptic inflammatory disease that causes increased synovial fluid to leak out and irritate the surrounding tissues, which can also cause lateral hip pain. Frequent hip stretching, such as practicing dance, irregular movements can cause chronic strain on the hip muscles, which can also cause lateral hip pain. Lumbar disc herniation, spinal stenosis and other compression of the spinal cord nerve roots will also appear on the outside of the hip joint depression often pain symptoms. Pain can also occur if the bed is too hard at night and the outside of the hip joint is compressed. If there is frequent pain in the lateral hip joint depression, it is recommended that the patient go to the hospital for medical examination to clarify the cause of the disease and receive regular treatment.
