I'd be interested too. I have had L4-5 stenosis with disc degen for about 5 years. One MD wants me to have surgery. Not so sure, just yet. Pain meds don't work with being semi-comatose. Epidural injections x3 with 1 facet injection have brought the pain to a level of 3-7 depending on the day. Maybe acupuncture next???
I posted this same question on another General Discussion message board and I've gotten quite a few positive responses from people who suffer like we do and the inversion table seems to help. I think I'm going to take the plunge and buy one. I checked Craigslist, and there are few available in the Omaha/Lincoln area.
Best of luck to the both of us.
