I completely understand and relate.....I was carrying books, hardback books up a flight of steps, slipped, fell( I never learn). I just got out of a hot shower, took an Ibuprofen, a Darvocet and I'm laying on a medicine ball to stretch my pecs, chest. I had chest pain, arm pain an hour ago so bad.....I know what it's from. It's just the rest of my day is shot. Being on a laptop and driving the car do me in as well.....This pain exhaustes me
