Thigh muscle soreness after exertion can be relieved after general treatment and physical therapy if it is not caused by pathological factors such as muscle strain. 1. General treatment: muscle soreness after exertion is mainly due to the accumulation of lactic acid produced by the anaerobic fermentation of glucose, you need to get enough rest and drink plenty of water to promote the discharge of lactic acid, which can relieve the soreness. 2. Physiotherapy: For example, massage and hot compresses can promote blood circulation in the legs and accelerate the discharge of lactic acid, which can alleviate thigh soreness, and can usually be recovered in 2 to 3 days. When the thigh muscle soreness is still not relieved or aggravated after the above measures, it is necessary to consult a doctor in time to find out the cause and standardize the treatment under the doctor’s guidance.
