Pain on both sides of the buttocks after exercise, generally speaking, the common causes are mainly the following: a. When patients exercise vigorously, the muscles of the buttocks contract strongly, which can cause a large amount of lactic acid and other metabolic wastes to accumulate, thus causing local pain symptoms. At this time, patients need complete rest, hip muscle massage and physiotherapy, and can be given hot ointment packs for external application to promote the absorption of lactic acid and other metabolic wastes and relieve the pain of the hip. Second, the patient is too strenuous during exercise, causing strain on the hip muscles, accompanied by the formation of local hematoma. At this time, the patient’s pain symptoms are often very obvious. It is necessary to go to the hospital as soon as possible to improve the local ultrasound examination to clarify the size and scope of the hematoma and assess whether there is active bleeding. Try to give local ice packs for 24 hours to reduce tissue exudation. After 24 hours, oral bruising pills and topical blood-stasis ointment can be applied to promote the absorption of the hematoma, and in some patients, the hematoma in the hip can be completely absorbed after 5-7 days.
