for the last three or so days, it has felt like my heart is running too fast. occasionally my chest feels tights.
i was at the hospital the other day and sneakily checked my heart rate and SATS when nurse was out of the room and they were normal.
i did use to have panic attacks, and it sort of reminds me of that feeling. but am not sure. and obviously the more i worry about it the worse it seems to get.
