Hey guys for a while now I have had the feeling of restricted breathing as if I'm being smothered, most of the time it feels like its in my throat. Once or twice now I feel like I'll stop breathing, my anxiety is cleared but I have Hypothyroidism I know this maybe the cause but I wanted to make sure. For all you medical nuts out there My BP stays around 120/70, oxygen sats 96-99% ad pulse around 52-90 irregular. Please advise.
