Recently, for the past 4-6 months my left armpit and left saide of my chest around my heart seem to burn and feel weird, like tender to the touch its not a horrible pain or anything, just discomfort. It happens most of the day, also when I put my hand over my heart, my heartbeat doesnt feel too strong at all. I can spit up mucus on demand, which has also been going on for awhile, its clear and very sticky. I havent smoked in months, I barley drink, and im 21. please help enlighten me.
