m exercising, sitting at the computer, laying down/reading (although I notice the pains more if I lay on my sides). I had one, instant-long, sharpish
pain in the
center of the chest and near my right scapula. I've worked out for 35+ minutes, moderate-low intensity for the past three days. Two days I had pain, one day I didn't. I haven't been out of breath (more than usual). I haven't been able to pin down how long pain lasts as it seems to not really have a pattern.
