I had the pleasure of having someone plow into the back of me during a moto this Sunday and my back has been killing me ever since and I need some advice. Its my lower back that is hurting. My muscle pains that I usually get everyday after I race (I'll be 39 next month) are now gone but my back pain is still severe. It feels like a pinched nerve. If I sit long I cannot get out of my chair without pulling myself up. After I'm up I have to stand and stretch before I can walk. I have an important race coming this Sunday and my question is: Should I stretch or should I rest my back? Would 20 min heat then 20 min ice work on a pinched nerve? Should I hang upside down? Help. Thanks for any advice.:( :(
