Leg and stomach pain by pressing may be caused by physiological reasons such as strenuous exercise, and pathologic reasons such as lumbar diseases, vascular diseases and fascial gap syndrome. 1. Physiological causes: mainly due to strenuous exercise, prolonged standing, cold, calcium deficiency and other factors, physiological causes will cause muscle tension, spasm, slow blood circulation, muscle fatigue injury, acidic metabolites such as lactic acid, oxygen free radicals and so on the accumulation of aseptic inflammation, stimulation of the peripheral nerve roots, the emergence of pain symptoms. 2. Pathological causes (1) Lumbar diseases: such as lumbar disc herniation, lumbar spinal stenosis, lumbar spondylolisthesis, etc. because of the stimulation and compression of the nerves innervating the leg and stomach area, which will cause pain in the leg and stomach by pressing. (2) Vascular diseases: venous thrombosis, arterial occlusive vasculitis, varicose veins of the lower extremities, etc., will lead to obstacles to blood circulation in the muscles of the lower extremities, resulting in the accumulation of acid metabolites, and the emergence of pain in the legs and stomach by pressure. (3) Fascial gap syndrome: because the calf gastrocnemius muscle is squeezed for a long time, causing ischemic necrosis of the gastrocnemius muscle, causing fascial gap syndrome. You need to go to the hospital in time for consultation and treatment. There may also be other causes of pain in the leg and stomach, such as calf fracture and calf bone tumor, etc. It is recommended to go to the hospital in time, improve the examination to clarify the cause of the disease, and then give targeted treatment or treatment under the guidance of the doctor.
