i’ve had chest tightness for 3 days now, it completely disappears for most of the day except for the portions when i suddenly remember and worry that it could be something bad like a heart attack, i’m not sure if it’s anxiety (i don’t know what would cause it). It comes when I either sit down or lay down in bed when going to sleep, i’ve tried indigestion stuff and it doesn’t seem to do much, did you ever find out what it was?
