Suffering now for 7+years. 2012 DX with Fibromyalgia. Misdiagnosed with MS 2018. 2019 Positive Gluten Intolerance, Small Fiber Neuropathy and now Stiff Person Syndrome. Ivig treatments for past 6+months with minimal affect. Neurologist referred me to Hemotologist/Oncologist due to very high GAD-65. Hemotologist/Oncologist recommended whole body pet scan. Now pending insurance for over 2 weeks. Just received call from Hemotologist/Oncologist stating SPS is Neurological and can't understand why my Neurologist referred me to him. He told me he will get in touch with my Neurologist to find out what prompted him to refer me. This was same discussion over 2wks ago in his office. I honestly feel I'm in the twilight zone. I do realize SPS is extremely rare, but can't one of my doctor's atleast point me in the right direction? Any recommendations on who or where to go for this would be appreciated.
