I hope by now this has stopped, but, in any event, I would certainly see your doctor to rule out any majour heart issues. It may be anxiety, usually is, but, it is always best to err on the side of safety.
I am so very sorry that I am tardy to your urgent inquiry. Please let us know how you are doing.
If you haven't consulted your PCP I encourage you to do so, even if the symptoms have resolved. This could be indicative of a cardiac issue, GERD or other medical issues. It's important that you get these symptoms evaluated. Again I hope you have done just that.
I've been absent from MedHelp for sometime and have recently returned. I'll look forward to your reply, indeed I'll watch for it.
Take Care,
