The pain doctor and neurologists tried treating my pain(which is the worst thing to live with for me) with Fentanyl
, Dilaudid, etc. and Tegretol, Lyrica, as well. I find it helps for a while, and then either wears off, or when it gets cold and rains I get worse. On my last MRI 3 weeks ago my Chiari has looked to be getting worse, and USC is arranging a standup MRI soon.
