I hope you have an atty fighting the deg disc dx. If you didn’t have any issues prior to your accident or other test showing the disc issues prior to your accident you should be getting that covered at least from a sprain\strain perspective. I did have a small prior disc bulge neck which I ack up front and had 2 semi recent MRI's due to that - since the accident there were a few more and the one that was noted was worse so in terms of size I suppose. In any case I now have tingling, arm and hand pains and radiculopathy pretty constant all day. (I do believe this is mostly neck related) meds help reduce the pain but the flare ups make it hard to continue what I am doing without taking a break, laying down etc... So all in all the accident has made this a chronic issue for me. I am also dealing with the head injury. Different type docs dealing with each issue so there is a lot going on.
