Numbness in the right leg may be related to many diseases and is considered a precursor symptom of lumbar disc herniation. Patients suffering from lumbar spine disease will experience lumbar acidity, pain in the lower back, pain in the location of the sciatic nerve, and numbness and weakness in the legs. CT examination of the lumbar spine can be done to determine the diagnosis before treatment. If the right upper limb feels numb and usually has high blood pressure, high blood lipids, headache and dizziness, it may be related to cerebral infarction, cerebral thrombosis and cerebral arteriosclerosis, and blood pressure, blood lipids, blood rheology and head CT examination can be done. Numbness in the right leg may be related to local nerve injury, improper activity, poor blood circulation and poor circulation in the lower limbs due to prolonged maintenance of a posture, which should be diagnosed and actively treated as soon as possible.
