The most common cause of pain in the buttocks after exercise is due to strenuous exercise, resulting in excessive lactic acid accumulation in the hip muscles, inflammation of the fascia, and consequent pain. The pain is mainly characterized by soreness, swelling, and occasionally radiating pain along the buttocks toward the back of the thigh and other areas. Localized pain can be induced when pressing with the hand, but can be comfortable when tapping with the hand, which are typical clinical signs of myofasciitis. The best way to deal with this condition is to take sufficient rest to relax the local muscles, which can be done by massage or hot compresses. Simple hot compresses can be applied with hot water bags or hot towels, and infrared therapy or moxibustion can be used if available. If the pain is severe, you can also take oral non-steroidal anti-inflammatory and analgesic drugs, such as Xilabao capsules or Nimesulide dispersible tablets. In addition, you can also use topical medications, such as topical application of Fotalin ointment or topical application of blood circulation and analgesic cream, Luofuoshan rheumatism cream, etc.
