Wow what a coincidence! I was browsing the internet just now because I am having the exact same thing. It's around the vicinity of my heart--and I don't like to jump to conclusions, but I don't want to ignore it either. I've experienced this in the past but I ignore it. But lately I've been having other weird symptoms that have gotten me an appointment at a prominent medical center here in Tennessee. I just want answers really because it is all quite worrisome.
