Herniated disc has been relieved can foot wood aggravation, mostly consider the nerve damage has not yet recovered, if the patient is after surgery, but also need to consider the situation of postoperative nerve adhesion. 1. Nerve damage: After nerve compression caused by lumbar disc herniation, no matter whether conservative or surgical treatment is adopted, although the condition can be relieved to a certain extent, the nerve compression can only be recovered slowly through time, and the recovery time is positively correlated with the degree of damage. 2.
