Numbness in the leg from a compressed nerve in the sciatic does not mean that it is almost over. If a herniated lumbar disc or stenosis of the spinal canal compresses the sciatic nerve, it can further produce symptoms of nerve damage, pain, leg numbness and so on. When sciatica gets better, there is often a significant reduction in the symptoms of hip pain, prolonged intervals between paroxysms of pain, the gradual absorption of inflammatory substances, exudate reduction, muscle spasm is gradually relieved, and the patient will suddenly feel relaxed in the lower back; when the condition is alleviated, the radiating pain in the lower limbs is reduced, and the discomfort such as aching, numbness and distension are also significantly reduced, and the muscle soreness is alleviated, and the patient will obviously feel strong in walking. Usually, the recovery of nerve function is relatively slow, generally may take more than half a year. The exact time depends on the individual’s ability to recover and heal.
