Hip injection depressed muscle atrophy is usually difficult to recover on its own, and some can be relieved by treatment. Depressed muscle atrophy after buttock injection is caused by local muscle degeneration caused by repeated injections in the same area over a long period of time, resulting in the formation of scar contracture and muscle atrophy. So that the muscle structural changes, this situation is difficult to recover by itself. If there is only a simple depression without symptoms such as limited gluteal muscle activity, generally do not need to deal with. If the scar contracture is obvious, it may affect the function of the hip joint to form gluteal myoclonus, limiting the hip joint activity, then it needs to be treated, usually through surgery to cut off the contracture part of the muscle can be relieved. If the symptoms of hip injection depression muscle atrophy, it is recommended that patients go to the hospital to improve the examination and receive regular treatment.
