Recently I've had this upper abdominal/lower chest pain that isn't too deep at all. It feel like many pin pricks, or razor blades cutting inside my maybe 1-3 inches deep into my fat layer and maybe just underneath. It's semi widespread across the general area of between my lower front ribcage in the upper abdominal fat area/lower chest area. It seems to sometimes get set off after I bend over(the fetal position) and may be made worse by a deep breath. it doesnt feel deep enough to by in my pancrease of stomach, what could this be?
