I'm sorry your sick! I know how u feel yr not alone! Answers are so hard to find.im told I have Chiari malformation and a cyst on my spine and that's cause ing me the same problems as you,but I also have the worst nerve pain on my left side! Pain meds dnt help,lyrica does a little! I've been sick for over a year now and the pain is too much! I don't want surgery on my head!! Hope you feel better soon, I'll pray for you!
