How long it takes to recover from lumbar nerve compression and leg numbness needs to be judged according to the type of disease and healing ability of the patient, and cannot be generalized. If the patient is due to long-term maintenance of a movement, posture caused by leg numbness symptoms, after 3-4 hours or 1-2 days will be able to return to normal. However, if the patient’s leg numbness is caused by a lumbar disease, the patient will not recover from conservative treatment alone and will need to go to a hospital spine clinic for surgery if necessary to completely relieve the symptoms of the compressed nerve, which usually takes 3-6 months. In addition, if the patient’s nerve function is very slow to recover, it usually takes more than six months to recover. If the patient’s nerve function heals quickly, the recovery time can be shortened accordingly, taking about 2-3 months. Patients are advised to live and work in accordance with medical advice and maintain good habits while undergoing regular treatment. During the recovery period, pay attention to more rest, avoid straining, avoid sitting for a long time, sleep on a hard bed and avoid weight-bearing on the back.
