Any suggestions for severe lower back pain?

My husband has slipped his disk in his back. He was crawling on the floor the pain was so bad one day when I came home. He has never taken any medication and his will be 40 years old next month. He fought taking pain pills, because of all the addiction problems he has heard of. He did A LOT of research and decided that an inversion table would be the best for him. That table now sits in my lovely dinning room/ living room area! Lucky me, but it works. At first he hug upside down a little bit and with time grew. He has no pain from the slipped disk. When it acts up, he just hangs upside down and it helps instantly. He tells me its about decompressing the spine. He loves it and takes no meds. The table was 100.00 and that is a one time payment.

Hope this helps
