I have been on T3 only for 3 years and on a stable dose of 55mcg split into 3 doses. I have noticed at times that I get a fast pulse in my neck as the T3 reaches its peak - usually I only get this when I am ill. This week I have had very painful trapped nerve in my arm and was taking paracetamol and got it then.
Tonight (not taking the paracetamol today but had used a TENS machine instead) I had a very odd feeling in my chest straight after my meal and my pulse was very high at 91 so I lay down flat. I am guessing that this is to do with stress and adrenalin as the pain this week has weakened me. f I take my BP it's fine - maybe high for me, but my natural BP is low, but the pulse can be higher at these times.
Would it help to lower my dose of T3 a bit at such times of illness or stress - would that help to reduce the effect of the high heart rate?
