Patients have sore legs after standing for a long time because they are prone to muscle fatigue damage in the lower limbs after standing for a long time, which affects the normal acid metabolism in the muscles, resulting in localized soreness and swelling. If the patient stands for a long time, the venous return of the lower limbs will be blocked, or the normal flow of qi and blood in the lower limbs will be affected, resulting in stagnation of qi and blood stasis and blockage of meridians, which will also cause soreness and pain. After the patient has leg pain, he should stop standing and rest in bed, and also elevate the lower limbs, use hot towels, take a hot bath, or use massage, which can significantly relieve the pain.
