Calf soreness often occurs after climbing stairs, which is a normal physiological phenomenon. The solution to calf pain is mainly the following: First, improve the exercise habits, try to avoid climbing the stairs, instead of taking the elevator, can reduce the lower limb joint muscle overactivity, to avoid the calf pain. Second, for patients with long-lasting soreness, local hot towel wet compresses and manual massage physiotherapy can be given to reduce the accumulation of local lactic acid, thus reducing the pain symptoms. Third, if the patient’s soreness is still not relieved after physical therapy, he or she needs to go to the hospital for local ultrasound examination to clarify whether there are venous thrombosis, varicose veins and ligament strains in the lower limbs. After finding the abnormality, active symptomatic treatment is needed to avoid delaying the disease.
