Hi, About a week ago i noticed my heart (from that area atleast) makes a weird gurgling, popping, clicking sound is the best way to describe it, when i lay or lean on my left side. i can feel it in my chest, its pretty audible without stethoscope. the same thing happens if i run even for a very short period of time, thats also the only time it is painful, after running. Any medical term you can give me for this so i can look into it?
