Thought I'd check with some seasoned experts! I've been having this "flutter" sensation, in the middle of my chest, more up by the base of my neck (or between the base of my neck and throat), but right in the center. It's really a quick thing, like a single spasm if that makes sense...like a catch when you exhale.
At first a few weeks ago, I noticed it in conjunction with the end of a chest cold I was having. Would at first only notice it at night and when laying on left side. Occasionally I'll get it on my right or when I'm sitting. I've not noticed it when walking or doing anything.
I've mentioned it to my doctor and he doesn't seem too concerned. So, thanks for the time! Does it sound like a "palpitation" or heart flutter or something more bronchial?
