Hi Aussie and Mrs D, thanks for reply, yes it's a full body CT scan, I know it's a lot of radiation, I guess I'm just desperate to find an answer to this SFSN. Mrs D I did have a head and Neck MRI 2 years ago when all of this started, it showed that I suffered migraines, which I do, but no MS or tumors or strokes of any kind.I think I may hold off on the CT scan, I'm just so frustrated with being in so much pain with all of this, I just want to literally jump out of my skin! So Aussie did you have Full Body SFN and how did yours present? Thank you for all your help. Blessings, Jan
