Before I had surgery the neurosurgeon told me keep doing what I'm doing. Which at that time was the inversion table, the Rumble roller and other assorted exercise. He couldn't see where it was hurting me so why bother stopping. Did it help me? I can't really say one way or the other. I just had my 1 week post-op yesterday and he told me to start exercising again minus the inversion table for the time being.
Take it for what you will the thing that he told me to stop was the running. My feelings aren't hurt. The Inversion table while the idea is thousands of years old it's one of those things where the proof is all anecdotal and there's no hardcore scientific study behind it. If there is show it to me because I couldn't find any. Logically it certainly makes sense. Just ask Roger Teeter. I'll bet his wallet is bulging, not to mention his disc.
