Butt pain after running can be relieved by rest and massage if it is a transient physiological pain. If it is caused by strained hip muscles, it can be treated by rest and medication. During running, due to the anaerobic fermentation of the hip muscles, a large amount of lactic acid will be formed, and the accumulation of lactic acid will cause physiological pain. The accumulation of lactic acid will cause physiological pain, which can be relieved by rest, hip massage and slow walking to promote blood circulation and lactic acid absorption. If it is caused by incorrect posture or excessive intensity during the running process, it is necessary to pay attention to rest, avoid strenuous activities and long time walking. You can use ice to apply cold compresses to the painful areas, and take anti-inflammatory and analgesic drugs such as nimesulide and diclofenac sodium to relieve pain.
