Hi I have been experiencing some weird symptoms recently, I have a low basal temp and a resting heart rate of 55 bpm. recently I have been feeling as though my heart is skipping a beat and I feel as though I am breathing through a sponge. I have a diagnosed nodular goitre but I have had blood tests and they came back as within normal range. I mentioned these problems to my gp on the last visit and he just looked through me. I feel mostly tired and prior to the goitre my heart rate was about 70 bpm. How can a 60 year old who has done little exercise for the last ten years have the heart rate of a triathlete and still not get any response from the gp? I have 80% of the classic symptoms for Hypo, but my gp will not refer me or do anything other than the basic blood tests. Sorry for the rant but I have been fobbed off again and again and I am getting too tired to fight them anymore.
