I had a back problem about 2 years ago that was initiated by helping someone move.
I had excruciating pain in my right leg, probably the worst pain that I've every had in my life. My right leg was numb from the knee down on the left side. The doctor immediately had to prescribe narcotics because of my pain.
I went to a neurologist who did all sorts of tests and basically did nothing to help me. The neurologist told me I wouldn't be able to run again. It turns out that I had 2 bulging disks in my lower back. I reluctantly decided to try a chiropractor and after a couple of visits I noticed that the pain was subsiding. The bulging disks seemed to have healed themselves.
I did some research and decided to get an Inversion table. I have been using it ever since and have not experience any more back or leg problems. I have also been running since then and have not had the back problem resurface.
Here's a photo of the Teeter Hangups Inversion Table.
