Hi welcome to the boards though I am sorry for all you are facing. I am not an expert but there are many on here that I am sure will be along to help. An mri though did come to mind and if you had one? If not I would. Have you seen other specialty doctors? Anything in your life pre all this that you may have not noticed as serious but now could be a connection? Being sick,exposed to something,fall etc? Sorry I am not more help. Hang in there
