rapid heart rate?
I know it's not typically a symptom of hypothyroidism, but I have a pretty rapid heart rate - about 90-95 beats/minute. I'm on 20 mcg of levothyroxine, and would like to be on more because I am exhausted all of the time. But my doctor won't give me more because he doesn't want my heart going any faster than it already does. Anyone else having this problem?
