I am one year post RAI and self medicating on 2.5 NDT. Recently i have been feeling very unwell indeed,pain flare ups and more recently some pain in my neck. I was so concerned i had some private bloods done, I see my crp is high at 15 and both my thyroid antibodies are high one lot being at 4000. I was singed off by the endo months ago when she considered me stable on levo. I wondered if anyone who had RAI had pain int he next this far on and if any may had these high antibodies. Not sure what to do about them.
