i feel for you it's agony when your back gives in, my eldest son has been off work for 4 days as his back went last week, he was screaming in agony just as it went. the doc gave him anti-inflamatories and told him he's trapped a nerve, he went back yesterday morning but only lasted an hour, had to come home as he just couldn't do the job. now he's taking a week off paid holiday to rest it. My daughter gave him some movelat gel , she has slight curvature of the spine and needs to use it often, apparently it does help my son alot. she gets it on prescription under the name salicylic 2%mucopol ysacco (I've got a tube here that I used a few months ago) . Not sure if it can be bought. deep heat and ibuleve gel didn;t touch my son's pain.
