The symptoms of hip muscle atrophy are as follows: if the hip muscle is atrophied unilaterally, the skin will be loose and there will be a decrease in hip muscle volume, and there will be numbness in the hip. In the case of bilateral hip muscle atrophy, there will be a decrease in bilateral hip muscles and a decrease in muscle volume, which will result in a more relaxed skin on both sides of the hip, and the hip circumference will be significantly smaller than normal at this time. The symptoms of hip muscle atrophy are mainly due to the following reasons: 1. after lumbar disc herniation compresses the nerve, there will be hip muscle atrophy and sensory loss; 2. when there is hip inflammation or local intramuscular injection, hip muscle atrophy may occur after the nerve in the hip is affected. If the nerves in the buttocks are damaged due to intramuscular injection, pain in the buttocks may also occur.
