I get this thing described as exercised induced asthma, I can not run or do any high cardio, 2 minutes in and I'm fighting for air, my body turns bright red and it takes me hours to recover, the next couple days afterwards I can't function. Household chores get ignored cause all I can do is lie down or sit, getting up to use the restroom physically exhausts me.
Does this sound like PEM, I've had it since I was a child bit it's gotten increasingly worse walking to fast causes immediate breathlessness and pounding heart (even though my pulse rate is normal it doesn't even match up with my pounding heart feeling)
I have many other weird symptoms, but I've noticed Pilates exercise puts me out for two - three days and all I do 5 minutes that's my Max before creating an asthmatic reaction.
And running causes severe muscle fatigue, vomiting, closed air way, upper chest pain, but no one knows why it's close to an allergic reaction .... got me out of running the mile in highschool. Most of my symptoms got severely worse after experiencing strep throat 6 times in a three month period when I was sixteen turns out I had mono, I've steadily gone down hill since then
