Bobbielinks, thanks for the info on the surgery, it is most helpful. I have 4 bad disc's in my lumbar spine with arthritis on top of arthritis and sciatic nerve involvement. Also, have 3 baddies in my neck and scoliosis. Eight years ago my pain management Dr. gave me a nerve block for the right side and it lasted for 7 yrs... Last April ( when i couldn't bend over or sit down) he gave me block in the right sciatic nerve with no guarantees as to how long it would last. I was to return in two weeks for the left side to be done. However, I no longer had any sciatic pain in either side, so we put that on hold. Still no sciatic pain, but, I'm just really stiff and can't do much walking or bending over for very long---have to take many sit down breaks when vacuuming. LOL. Too many knock down dragged out battles with foals. LOL
