There are many reasons for daily calf soreness and distension, common causes include over fatigue, weakened blood circulation in both lower limbs, bone cysts, etc. It is necessary to choose the appropriate treatment for the cause of the disease. 1. Excessive fatigue: after strenuous exercise and too much walking, the local metabolites in the calf will increase, and the accumulation of lactic acid can cause soreness and weakness of the calf muscles, which can be gradually recovered through local massage, hot compresses and sufficient rest. 2. Weakening of blood circulation in both lower limbs: commonly seen in occlusive vasculitis, arteriovenous thrombosis in both lower limbs can lead to weakening of blood circulation in both lower limbs, resulting in soreness and swelling in the calves, weakness and pain, etc. Lipid regulation and stabilization of plaque, thrombolysis and other treatments can be adopted to avoid kneading and pinching of the legs. 3. Bone cysts: Bone cysts, if large, can cause pressure on the blood vessels of the calf muscles, causing blood circulation disorders, resulting in calf soreness and distension, which can be diagnosed by bone radiographs, and if necessary, surgical treatment is feasible. There are many other reasons for calf soreness and distension, and it is recommended to consult a doctor in time after eliminating the physiological reasons, so as to clarify the cause of the disease and then target the treatment.
