Does anyone ever get the feeling of their heartbeat being spasmadic or irregular? I get this weird feeling on the left side of my chest right under my breast as if my heart is humming or buzzing and at the same time it's like a muscle spasm type feeling, but seems different. i can't tell if it's actually my heart beating weird or something else. It comes and it goes, but for some reason I notice it alot when I sit down to eat. If anyone has this i would appreciate any comments you might have. Thanks!
