this is very interesting because my symptoms seem to be circling around and maybe because i've made a promise to my neuro never to google my symptoms so i currently don't have any new input.
here's a funny story. my HR was racing for 2 consecutive days. Always an average of 98-109BPM so i decided to go to my cardio. when i was there an intern/trainee was doing the preliminary check-up and he told me that yes my pulse is racing but that it doesn't seem to have any irregularities then he said we just wait for my cardio to be there. then my cardio arrived, took my pulse and it was only 70BPM. i told him you must be kidding me & he goes "go check for yourself" and true enough it slowed down. maybe i should marry a doctor??? i don't know haha!
