I have done all the test from my cardiologist and they still have found nothing. So now it s on to anxiety . Does anyone else feel like they are always thinking about it? I used to be able to get it to go awya after a few minutes, but now it seems to always be on my mind. If my heart isn t racing and I have no other symptoms I still have an uncomfortable feeling in my chest . Could this be in my head? Does anyone else feel this?
