I have had 2 spine surgeries (L4, L5) Discectomy 1st 15 years ago and the last June 2009. I was told at the last surgery I would have to have a fusion of L4, L5, sacrum. In the last few weeks, my back has been hurting alot along with my right testicle. I asked my Dr about this, and he said the 2 are not related. However, My testicle only hurts whne my back hurts and the Dr cannot give me another reaon for the pain. Is this because of the back pain? Also, if I do have the fusion, how much range of motion will I lose?
