Hi! I have had a mild throbbing pain in the middle left side of my chest that comes and goes. It's been doing it most of the day, and it's not the first time it's happened. I do take 2 medications for high blood pressure, and a medicine for anxiety. I haven't missed any doses, and have not had any anxiety in a long time, so I don't think it's that. I'm a 40 yr old female and have never smoked, but did grow up in a home of smokers. I drink a glass of wine on occasion, but only one, and not very often. Any ideas as to what could be causing this pain, and is it serious?
