Sore calves after running can be relieved by localized hot packs, muscle stretching, massage and acupressure. Sore calves after running are usually caused by the contraction of leg muscles, which produces a lot of lactic acid, resulting in a buildup of pain, which is commonly seen in sudden increase in exercise or running without preparatory activities before exercise. If you have sore calves after running, you can promote blood circulation and accelerate lactic acid metabolism by applying hot compresses or massage to the localized calves, thus relieving muscle soreness. You can also relax the calf muscles through muscle stretching to promote the recovery of spastic muscles. In addition, you should pay attention to rest, avoid strenuous exercise, and seek medical advice as soon as possible if the pain persists without relief. When running, it is recommended to do preparatory activities first, and pay attention to the right amount of activity to avoid calf pain again.
