There are two main reasons for the pain in the buttocks: 1. It is due to strains and strains in the buttocks muscles such as the gluteus maximus, gluteus medius, gluteus minimus and pear-shaped muscles, such as strenuous exercise and too much activity, and the long-term fatigue and strain of the local muscles will lead to the formation of strains and strains. The formation of local inflammatory edema and bruising and swelling will stimulate the peripheral nerves and cause painful sensations. This is especially true when pressing or moving the lower extremities with your hands, as the muscles are stretched and stimulated, leading to more pronounced pain, which can be alleviated when resting in bed. 2, is due to sciatic tubercle bursitis, which is caused by frequent sitting and a hard bench, leading to the lateral bursa of the sciatic tubercle, which is a fat pad that is continuously squeezed and stimulated for a long time. This can also lead to inflammation of the bursa. This can cause irritation to the surrounding tissues, which can also cause pain.
