There are many causes of calf muscle pain, such as calf muscle strain, varicose veins, lack of calcium in the body and so on. Different causes have different treatment methods, common treatment methods are massage, physiotherapy, medication and so on. 1. Calf muscle strain: when using the legs for too long with too much intensity such as long standing, walking, sports, etc., the calf is too tired, the calf muscle accumulates a lot of lactic acid and other metabolites, causing muscle soreness. The symptoms can be relieved by stretching the calf muscles, applying hot compresses on the calf muscle parts and massage to promote the decomposition of lactic acid. 2. Varicose veins: Varicose veins can lead to obstruction of venous return in the lower limbs when standing for a long time, and blood pools in the calves. This causes muscle pain in the calf area. You can rest in bed, elevate the affected limbs and wear compression stockings to avoid further expansion of the veins and relieve the pain symptoms. You can also take medicines as prescribed by the doctor, such as Diosmin tablets and other vasoactive drugs, to increase the tension of the vein wall and promote venous return. 3. Calcium deficiency: when the patient lacks calcium, it is easy to trigger calf muscle spasm resulting in soreness and pain. Usually, attention should be paid to supplementing high-calcium food, calcium tablets and so on. Vitamin D should also be supplemented appropriately to promote the absorption of calcium. In addition, sore calf muscles may also be caused by arterial diseases such as arterial embolism, nerve and blood vessel compression in the lower limbs such as lumbar disc herniation cervical vertebrae is lumbar vertebrae slipped and so on. It is recommended that patients with calf muscle pain go to the hospital to identify the cause of the disease and treat the symptoms under the guidance of the doctor.
