Thank You very much for your response and the links you provided.
I first got numbness and some mild irratation after a total hip surgery. The surgeon stretched the nerve a little too much and getting better over time was not the eventual result. It has become more of a concern over time although I do not have to take any sort pain relief medication.
The numbness in my left foot and ankle showed up after the second back surgery. Both of the surgerys were done to relieve pain radiating down both legs. I also have a stenosos which complicated both the conditions which resulted in a surgical intervention.
The numbness in my left leg is a nuisance but once again, I do not have to resort to pain medication for relief.
I should also add that I take a low dose of Lirica twice a day which was prescribed after the second Back surgery.
After reaqding some of the stories about intractable pain, I consider my self very lucky.
