The sides of the hips of normal people are plump, and only people with a thin body type or other diseases like femoral head necrosis may have depressions on both sides of the hips. If the depression on both sides of the hip is accompanied by soreness, the following cases should be considered: First, femoral head necrosis causes the femur to collapse, resulting in depression on both sides of the hip, which causes painful sensations. Secondly, prolonged standing will lead to excessive hip joint activity, thus causing muscle damage and poor blood flow, which will cause soreness and pain. Third, may be due to lumbar spine diseases such as lumbar disc herniation and other compression of nerves, resulting in soreness and pain. If there is such a situation, it is recommended to go to the hospital in time for further examination to clarify the diagnosis and carry out the corresponding treatment.
