I have very bad asthma that when I run around or exercise it makes it hard to breathe, but this is different. I am a gamer, and I usually play for around 3 -4 hrs a day. As I was playing, this extreme pain came at the upper left side of my lung \ rib. It especially hurts when I breathe in and move around. I can't bend down without it hurting. I am very concerned. Is it from sitting down for 3 hrs or is it something else?
