Inner calf pain is considered to be caused by physiological factors and disease factors such as strain, vascular lesions of the lower limbs, nerve compression and other factors, and should be promptly consulted. 1. Physiological factors If the patient walks too much and the calf gets cold, it can stimulate the inner calf muscle and cause pain, which can be relieved after resting and applying hot compresses. 2. Disease factors (1) Strain: If squatting, running, jumping and heavy labor are often performed, the muscles of the calf will be pulled repeatedly, which may cause injury and pain. It is necessary to pay attention to the intensity and amount of exercise, and avoid sports that cause greater damage to the lower leg. (2) Lower limb vascular disease: such as varicose veins of the lower limb, arterial embolism, etc., will make the blood circulation of the calf impaired, calf ischemia and hypoxia, and inner calf pain occurs. Compression therapy, medication or surgery is needed for the disease. (3) Nerve compression: lumbar disc herniation will compress the nerve, causing inner calf pain, accompanied by leg numbness, weakness and other symptoms, surgical treatment is needed to release the compression. There are many other causes of inner calf pain, and it is recommended that patients seek timely medical examination to clarify the cause and targeted treatment.
