So after not feeling at all well on 25mcg thyroxine I didn't take any more because of Xmas period (we had visitors for nearly a week!) I now have an appointment with my 'sympathetic GP' Friday to discuss medication. Should I have some tests I have never had like lots of people are suggesting just in case it's not my thyroid at all? I am sure he will oblige bearing in mind my husband came with me last time and gave him my symptoms and that he was 'fed up' seeing me like this. Main symptoms again (although nowhere near as bad as others), very cold all the time, legs/feet especially hurt when get cold, very low temperature before rising, badly constipated take medicine all the time, fall asleep all the time, having trouble holding down my very pressured job, hair thinning over years, nails awful etc. One thing I have mentioned before is I am still taking Premarin (HRT) every other day and have done for over 10 years. When I don't take for 2 days I feel awful. Any answers would be gratefully received! Thanks.
