If the thigh muscles are sore after exercise, you can choose conservative symptomatic treatment, pay attention to rest, local hot compresses, physical therapy, massage, and topical fotarine ointment can be used to treat the swelling and pain. If the local pain is heavy, you can take oral non-steroidal anti-inflammatory and analgesic drugs for symptomatic treatment. The soreness of the thigh muscles after exercise is mainly due to excessive exercise time or excessive exercise, resulting in excessive contraction of the thigh muscles, causing an increase in local lactic acid metabolites, resulting in impairment of lactic acid metabolism in the muscles, thus triggering soreness of the thigh muscles. If there is no relief within a short period of time, you must go to the hospital in time to choose a more reasonable method to relieve the symptoms of soreness as soon as possible.
