So I'm 29, I've had mild POTS for about 15 years, fibromyalgia for 4, and ET for maybe 2? I also have anxiety. I was diagnosed with ET a year ago and since then I can't really tell if there's been any progression, but recently I've been getting winded and shaky from some normal activities. Seems to happen after a walk, or maybe it's from going up the stairs to my apartment. Does this happen to anyone else? Sometimes it's so bad I have to just lay down for like 30 minutes, shaking and breathing laboriously. It also has happened after intercourse a few times. What is going on here? It's hard to convince myself this isn't in my head. I feel sort of unsure if this is worth going to my neurologist about.
