Had RAI in May but seen noone since, in my last post you told me to go to Doc (didnt like to to be a fusspot) as am feeling terrible with headaches. Thank you so much, I was having some really bad days, but now know why. He did tests and my TSH is 61, FT4 2.6. Started me on 25g thyroxine, says I need to go to 150/200 but it will take time as bp so high he cant give me any higher dose. How long before I see any improvment, I live on my own and this is really a difficult time? Thanks.
