wow... i am reading this outloud and my husband said... that sounds like you...
i have every symptom you have and more and have been diagnosed with fibro as well.
such a crazy mess of pain and what I call "weird" symptoms, such as chemical sensitivities, numbness and tingling in fingers, hands, arms, feet and pain that shoots all over the place, and many others. I've been to all kinds of specialists including a neuro guy because I thought MS would be very possible and it does run in my family. But my tests came back normal as well for MS.
I also have severe (but completely inconsistent from day to day) cognitive and memory issues. They are calling it fibro fog. Maybe. Maybe fibro truly IS the cause of all my problems.
I had finally resigned myself to that but last week when my fibro doctor noticed white spots on my legs (otherwise tan, but multiple spots of complete white), and noted that I have balance problems that cause me to fall (mostly I just veer off to the right and bang into the wall or whatever is in the way .. or just fall if nothing is there to catch me)... he suspects something called "dysautonomia" and suggested I see a neurologist and if that isn't conclusive to go to the mayo clinic.
He is the third doc to suggest another trip to the neuro and also the third doc to suggest mayo clinic. The other docs recently suggested a neuro because I have been dislexic in so many ways. Started out with numbers, then letters, then actual words (such as saying "left" when I mean "right"). And because of the numbness and tingling in my fingers and right arm...
I have a neuro appt in about a week and if that is not conclusive I am going to finally do what they are suggesting and try the mayo clinic.
I also forgot to mention that I have had every kind of bloodwork known to man including thyroid, B-12, sedrate, ACE, several Lyme titers, cbc's, etc, etc. Also, my tongue twitches occasionally, just like the rest of me.
