Hi, had a small accident two weeks ago. Whiplash and concussion plus muscle damage. The worst thing is the concussion. I've been scanned for bleeds etc. Nothing found. I've never felt anything like it. My head feels like it's being squeezed and the pressure on my neck is unbelievably painful. The nausea and vomiting is getting worse and so is the depression. I just need to know that this will get better. Going back to the doctors later. Can anyone give advice?
