Didn't something like this happen last year or the year before which ended in you damaging your back at work and taking time off, suing them etc.over the last few week my backs been giving me pain as i was working with a guy with a bad back who couldn't share the picking and loading
I would have thought that you back pain now is aggravated from the previous injury. Once one has had a serious back injury it will never be the same again. It will never be 100% healed and always a weak point. So take care Seb think about your back when lifting things mate. I find it best if once one feels any excess strain or twinging then it's best to stop right away. Catch it before it gets worse and rest the back from whatever your doing to cause it even if that means bed rest lying flat on your back for a couple of days.
