ouch! (((hugs))) If you have coverage already for your spinal issues, then I wouldn't bother with another claim. If you don't have coverage, and need some to address the exacerbation of the issues, then yes, get that. It won't be easy, as they will delay and deny claims, exclaiming that you already had "all those" pains and problems.

Talk with the doctor and see if he can make a clear delineation of your previous and current problems. Good wishes on this (((ww)))
