That is a tough one! I really feel for you on the back pain. My dad went through this for years and finally bit the bullet and had the operation. Seems like the more shots he got the less effective they were and the pills only do so much. The only regret he had was not having the operation sooner. I know it takes a while to get over it(In his case 6 months) but it was no comparison to the years of pain he went through. Tough choice.
