I have been having left chest buring sensation for approxmentley 2 months. A few weeks ago I was awakened by a very sharp shooting pain down my left chest, also my left nipple has felt like it was burning. The burning sensation goes away during physical activity and sometimes it will disappear for a few hours, usually this pain lasts for days and hours and hours at a time. 31 year old female, non smoker, overweight, I know my numbers with cholesterol.
