I would check it out with your Dr. I understand that it is not necessarily here nor there but in my case I had weird feelings like that and went for a nuclear treadmill. I did everything they asked of me and felt pretty good about it. They called me the next day with the news that I had two 94% blockages and one 70%. I have had two stents for seven years now. One of the blockages was not repairable.
If I were you I would err on the side of caution and let the Dr say that you are okay.
