so since i dont wanna bothering by making multiple threads i think i combine 2 topics at once. 1. i was wondering if people with dysautonomia/POTS/OI supposed to have no tachycardia/palpitation when exercise/do activity/exertion supine? maybe like lifting themself or something heavy. or push-up/sit-up. 2. i noticed i often get fever(or maybe slightly)/raising temperature with unknown cause for some days when i get sick/about to get sick. or maybe its the other way around. because the fever thats making it worse. (still clueless) by sick i mean like palpitation tachycardia, flu like symptoms, muscle ache, tired/fatique, etc. i wonder if its a sign or if people here also experience it.
