Muscle soreness and pain should be treated with hot compresses. Because muscle soreness is mainly due to muscle strain, such as frequent muscle contraction and relatively high activity, it will lead to muscle tissue fatigue gradually and form strain, gradually forming inflammatory edema, resulting in local inflammatory metabolites on the peripheral nerves around the stimulation, there will be a painful feeling. In addition, due to the large amount of activity and exertion, it is easy to have a sore and tender feeling. In this case, the application of heat can effectively increase the local blood circulation and promote the metabolism of inflammatory metabolites, and the pain sensation can be significantly improved after the stimulation of peripheral nerves is reduced. In addition, as the heat compress can also make the muscle tissue become more relaxed and less tense, the pain symptoms can also be improved. In addition, after the hot compress, it can increase the local arterial blood supply, which can make the muscle tissue get more nutrition and energy support, and the soreness can also be significantly improved.
