Before RAI, I never really had migraines but would get like a 'pressure ' feeling on the sides of my head....as if my head was in a vice (yes I know it sounds silly but thats the only way to describe the pain).
After RAI, I would sometimes get an occassional headache after increasing the thyroxin.
But I havent had headaches for months now...it was at the early stage after RAI.
When I asked my Doc, he told me that it was the hormone imbalance of FT3 and FT4,.
I too have Graves....maybe that will shed some light on the problem for you.
I think maybe its your levels balancing out...give yourself some more time.
And get your eyes tested.
I've not had Graves so I can't answer that. I used to get severe migraines when I was getting my very first periods at age 12. I wonder if you are having any hormonal problems at present? It would be a good idea to get it checked out anyway, regardless. Migraines can sometimes be a sign of something more sinister. Hopefully not for you!
Cheers
