The main reason for muscle soreness after practicing leg exercises is that the body produces too many metabolic products, caused by the accumulation of lactic acid, which can be relieved by rest, physical therapy, medication and so on. 1. Rest: you need to temporarily stop exercising, minimize activities, elevate the affected limbs, and rest sufficiently, the symptoms of muscle soreness can be gradually relieved. 2. Physiotherapy: Muscle pain can also be relieved by localized hot compresses, massage and other physiotherapy to promote blood circulation in the legs and facilitate the excretion of lactic acid. 3. Medication: If the pain is severe, you can apply non-steroidal creams, such as diclofenac diethylamine salt emulsion, etc., and you can also apply ointments, such as Yunnan Baiyao plaster, blood circulation and pain relief plasters, etc., to relieve the local pain. When performing leg exercise, it should be gradual and avoid strenuous exercise in a short period of time. If the soreness after practicing leg exercise cannot be relieved by the above methods, there may be other possibilities such as muscle strain, rhabdomyolysis, etc. It is recommended that the patient consult a doctor in time to identify the cause of the disease and then carry out targeted treatment.
