Well anyways just this past Monday while I was eating breakfast at McDonald's I felt a strange sensation in my left side of my chest near the armpit area.I felt numbness, tingly, sensation, then my heartbeat. It only lasted for 5 minutes or so. It was something that I don't recall ever feeling it before. It was an annoying feeling that caught my attention, then later caused me to panic and worry when I felt it again during lunchtime.Ever since then I keep feeling it more often. I started to obsess and worry about this that I don't know if its all in my mind and if my mind is making me sick.
