Hi bubblymags,
After getting out of hospital I was exhausted for a week, then the second week I felt a bit better. Because no one suggested staying off work any longer, I went back to work after two and a half weeks and gradually felt back to normal after maybe a month. But everyone seems to take a different amount of time to feel normal.
There seem to be various possible side effects (although I think I've been quite lucky and not had any). Over on another forum, a girl who recently had RAI is getting pain in her neck and I think her ears, and also lost her sense of taste. Someone else got a blocked salivary gland. Others have also mentioned dry skin and hair and weight gain. Could be I'm just used to being tired though, cos I don't feel I've had much energy for years!!!!
I definitely feel better on Thyroxine than I did on Liothyronine, which gave me a really fast pulse and heartrate, but my medication wasn't changed until after my follow up scan 3 months later. Your consultant will recommend a dose for you (maybe 100 or 150mg) and will alter it according to your blood results.
Mention your symptoms to your consultant, they might be quite common and they'll be able to advise you. x
