as mentioned earlier, try to find one used. Gravity is gravity, haha. I bought one for $25 on craigslist. A few years ago I landed funny on a jump while mountain biking. Didn't crash, but it felt like someone shot me in the back on landing. Had to walk home. 9/10 pain for a few days before I found the inversion table. Within 5 minutes of hanging upside down, my pain was down 50%. 3 weeks later I rode Moab pain free. YMMV, and I suppose it really depends on what pathology is really going on, but it can be a cheap trial.

That being said, and not knowing how old you are, just make sure you get checked out by a doc if not better in a week or so. Not all back pain is just arthritis, a pinched nerve or a muscle strain.

feel better!
