i think that's likely my case as well. i have frequent headaches, light and sound sensitivity, dizziness, fatigue, mood swings, and other ans symptoms that COULD be consistent with migraine, but with how related fibromyalgia, cfs and migraine are i think it sounds like misdiagnosis is far too easy in my case, especially with how little was done to investigate. not to mention that i do already have a fibro dx. i have a family history of migraine, and i have had at least one before, but the one i remember had causes separate from a migraine disorder and was in middle school. there was no mri or anything, i don't feel that my symptoms match up, and i think more than anything the neurologist wants to explain the ans symptoms i'm having as anything but cfs or pots. regardless i do definitely plan to bring it up with her next time i see her, because the intense pain and other side effects i have with it are hardly tolerable, much less theraputically viable... it's been no less than 4 hours since i took it and i'm still feeling distressingly sick and achy in ways i didn't prior to taking it. i'm glad i'm not the only one experiencing this because i could find absolutely nothing on it when i searched.
