You know I just thought about something I watched on television a few months back. This lady has severe pain and like so many of us, was tossed around from physician to physician. I don't believe she had seizures, but years after her diagnosis, she was finally diagnosed with a controversial disorder. I can't remember the name of this disorder, but a pain specialist at UCLA made the diagnosis.
Just from what I know about FM --- it sounds like it could be another neurological disorder.
Keep in touch and good luck !
my aunt thought it was cfm but with a mri it was ms instead so some times it can be trickey so i will pray 4 you and hope you will know soon :-]
