Thanks to you both. After finding out that too much ibuprofen can cause this, I stopped taking it. It has been 7 days, and the symptoms are all gone. I can be at rest and experience nothing but comfort, it's a blessing!
I have this the ones that kick like a horse was only caught once by a monitor and it was nsvt very short but there not saying that's yours sometimes its just a pounding heart. A single PVC to me feels like a butterfly in the center of my chest. As for stress I think is by far the worst thing for any person I have a lot more under stress. Just get checked out for piece of mind.
I postponed responding as I do not have any experience with your symptom, consider myself lucky. But seeing your post going "unanswered" I post the following:
1) Discuss with your doctor , at least your primary care doctor, ask for a Holter heart monitor if this happens every night - a Holter is a 24 hour test and if of on use if the symptom doesn't occur when it is active.
2) Sounds like a PVC, early or extra contraction of your Ventricle chambers. These are quite common and I believe mostly benign if uncomfortable.
Good luck, and best to discuss with your doctor.
