Leg numbness may be long squatting, lumbar disc herniation, diabetes, cerebral infarction, arteriosclerosis of the lower limbs and other reasons, need to be directed at the cause of the recovery of medication or surgery, the specific effect varies from person to person, there is no absolute method of rapid recovery. 1. Long squatting: prolonged squatting leads to lower limb blood running obstruction, arterial blood supply is insufficient, venous blood reflux is blocked, lower limb muscle ischemia and lack of oxygen and leg numbness. This is a physiological phenomenon, standing or lying down for a period of time can be restored. 2. Herniated lumbar intervertebral discs: Herniated lumbar intervertebral discs compress the surrounding spinal nerve roots, resulting in abnormal sensory function of the lower limbs, so the legs will be numb. The fastest recovery is through traction, acupuncture, massage, surgery and other treatments. 3. Diabetes: diabetic patients with poor long-term glycemic control will develop diabetic peripheral neuropathy, involving the lower extremities after the leg numbness, wandering pain and other sensory disorders. Eat metformin and other hypoglycemic drugs or subcutaneous injection of insulin to control blood sugar, and the application of methylcobalamin and other nutritive nerve drugs to recover the fastest. 4. Cerebral infarction: after cerebral artery stenosis leads to cerebral ischemia and infarction, the nerve function disorder that innervates the sensation of lower limbs will be numbness of legs. Recovery is fastest through thrombolysis, interventional therapy, application of cytarabine and other cerebral protective agents. 5. Lower extremity atherosclerosis: atherosclerotic lesions involving the lower extremity arteries lead to insufficient blood supply to the lower extremities, so the legs will be numb. Take atorvastatin, resuvastatin and other drugs or surgery and other treatments to recover the fastest. There may be many other reasons for the numbness of the legs, it is recommended to exclude the physiological causes of timely medical examination to clarify the cause of the disease, and targeted treatment. Pay attention to the use of drugs under the guidance of the physician.
