question: Hi i'm 27yr old male, a little overweight and i smoke, i have been having chest pain for about 2 months now, normally below the left nipple, like a stabbing, also pain under my left armpit and above my right nipple, i am being treated for acid reflux but have noticed my symptoms are worse when i don't poo, sometimes i dont go to the loo for 3-4 days, could this be a possible cause for this?
