I am 3 month post lumbar microdiscectomy for herniattion at L4 and am worried about symptoms I still have. Prior to surgery had severe burning in both knees, tingling burning, and numbness in both feet. My feet seem to be coming along ok, but knees are still burning. In fact, they are burning more now than they did in the first weeks after surgery. I read that they inject long acting steroids at the time of surgery and I'm thinking that maybe they wore off and that's why the symptoms seem worse. But I'm feeling very anxious about it. Could someone tell me if they experienced anything like this and did they eventually recover? Thank you.
