Herniated lumbar disc foot numbness is usually caused by the herniated lumbar disc compressing the corresponding nerves in the lumbar spine. The herniated disc will lead to compression and irritation of the nerves associated with the lumbar spine. At this time, it is possible to produce some numbness, weakness and other symptoms in the relevant parts of the lower limbs innervated by these nerves. The compression of the disc also affects the sensory function of the lower limbs, causing the patient to lose the ability to feel certain areas of the lower limbs. Thus, numbness occurs. Patients with this symptom should pay attention to bed rest, get out of bed activities to wear a waist cuff, after relief under the guidance of the doctor can carry out lumbar back muscle exercise. Patients with lumbar disc herniation who have symptoms of numbness in the feet should go to the hospital in time for examination and treatment.
