I have recently started using T3 alongside my T4.
I dropped the T4 dose & started on just 5mg of T3.
After 2 weeks I moved up to 10mg of T3 while dropping my T4 dose further. For 2 weeks I was feeling the best I've felt for ages & thought I had cracked things.
However one night I had a nasty experience. It started with a sinking feeling (like that scene in trainspotting where he falls through the floor), then my heart rate shot up 40 points, my blood pressure went up 50 points & I was having palpitations. My little finger started to tingle & I had mild chest pain (like a mild burning sensation).
I stopped the T3 & felt better the next day.
I know that the above can be a symptom of overdoing T3, but I want to know the medical reasons for the situation, as detailed as possible - as I find if I know the reasons for things it helps me deal with them.
I was very scared when this happened & honestly thought I was going to have a heart attack.
Does anyone have any knowledge of this??
