Although I had a different procedure (IDET), I was painfree the following morning (which REALLY surprised me).
Unfortunately, I have 2 other problems (sciatica & SI joint), which will NEVER be fixed. So, I guess I'm in a similar boat re: meds. Sucks, don't it?
I agree with Becky - take it slow, and TAKE CARE OF YOURSELF! Your health is the most important, just remember that.
Keep us posted...hopefully we can help or at least just be there for you!
