While I understand your pain (I have a 60 degree turn in my back) and everyone is trying to provide "treatments" which shocks me since if it were a snake we would tell you to go to the vet. No one on here is qualified to diagnose your issue and therefore cannot provide a treatment.

Heat - only works if your issue is muscle related it will make disk issues worse.

Cold - only works for inflamation and won't help if it is muscle related.

Pain Killers - Could mask the issue and cause more harm by making you think all is well and doing too much.

Chiropracters (sp?) - While do wonders on aligment issues if you have degenrative disk disease they can ruin your back permanently. My case (settled legally)

So you need to find a doctor who can diagnose you first before trying to find a home treatment you have to know the cause before you can fix it.

Hope this helps
