When I was a kid football playwer, without talent, speed or guts, I got cracked in the back making a bad handoff to the fullback (Shaughnessy Tight T)-- and off and on my back goes out so I know what you are feeling. I hope you have a good chiropractor - I taught law & medicine with orthopedic friends and love the orhto pods but take the chiropractors for work on my back. Hope you feel better soon.
