Hi I had a routine screening blood test a few weeks ago and it turns out that my TSH is 7. I had no idea I was low on thyroid but I had noticed that instead of my feet being always hot at night (usually sticking out from under the duvet) they are now always cold. In fact it's getting worse. This has been happening for I suppose 2-3 months now. My real question is that my pulse rate has gone down from about 70 (at rest) to just 60 and it feels really slow. Probably when I am asleep it gets even slower. This decrease has been over tha last month or so. Is this normal? It's another 2 months before I go back to the doctor for another blood test and the doctor told me they don't treat until TSH reaches 10. Should I go back to see the doctor and tell them about my heart rate having fallen? I hate to hassle doctors because I don't want to be labelled neurotic.
