I have started to have sudden 'attacks' lasting about 30 to 45 minutes where I have a pounding heart, breathlessness and feeling very spaced, weak and shaky.
There is no set daily pattern to it - It happens at different times of day but mostly mid day - have not had it happen in the evening so far. I am taking NDT in 3 doses - only one half a grain per dose so far - was still building up dosage.
I also get breathless on exertion and sometimes after walking dog for 30 minutes. Can this be a hyper issue and what should I do regards my thyroid medication?
Any advice please.
