I was involved in a car accident 5 days ago Im 40, 16 stone and have crohns disease. I was hit from the rear when I did an emergency stop the vehicle behind ran straight into back of me. I got out car but had to sit down and then was taken on a spinal board to hospital. Xrays were clear and I was told it was soft tissue muscular damage. However it is getting worse Im in alot of pain and cant take anything other than paracetamols - will this continue to get worse before better??? How long can I expect this to last??
