Hi, I had a nerve block right at about 2 months ago for a bulging disk in my L4/L5 on my right side. I have been feeling here and there the tugging and pulling as before, mostly right at my butt and top of my leg. So far none in the back. I was thinking I was feeling things again because I had started doing the elliptical and bike and maybe the muscles were not used to being worked, but now I'm not so sure if that's why. I do not feel it all the time, but I don't want to go backwards. Is that normal? Also, I feel a little swollen back there on the left of my spine...the opposite side of the bulging disk. My Dr. also said that it takes about 3 months to heal after a nerve block. I thought they never healed?
