Hi, I take 200mcg thyroxine per day and seem symptom free, healthy and fine. Recently, I stopped taking thyroxine for nearly 3 weeks (I know bad idea, but just happened with holiday, moving doctor surgeries and then a standard GP thyroid blood test for which I always skip a few days for as my results always suggest I am hyperthyroid and they tend to panic, even though I don't have one single symptom of hyperthyroidism).
However, since the birth of my first daughter four years ago by which I'd been taking thyroxine for about 2 years, I started to get headaches and migraines a lot (at bad times 3 a week, at good times 1 or 2 every 2 weeks). Each time I am pregnant (I've had 3 children now), the headaches stop and start again a short while after birth.
When I stopped the thyroxine for the 3 weeks, the headaches stopped apart from one right at the beginning, and no sign of one at all (I often have the suggestion of one starting from pain and tightness in my neck). I had a headache the day after I took the first dose of thyroxine again. I know it could have been pure coincidence, but I'm wondering whether there could be some link and something I need to do, like take T3 or change to Armour... I've no idea... Just wondering if anyone with more knowledge has any information?
