[I can understand..... Five years a go I went for nerve injections in my back as well as physical therapy. The first shot gave me no relief so I did not have shots 2 and 3. Finally had S4 and S5 fused together. Was that the right choice? Could no longer stand straight and was in constant pain.... so I think I made the right choice. The pain in my lower back has never totally gone, because the surgeon noted others areas that were showing slippage. If your first injection gives you limited relief you may want to ask your doctor if it would benefit you have. Thre injections are expensive, hope your insurance coverage is good.
