Hi there,
About two weeks ago, I started feeling a deep stabbing pain in my upper back underneath my left shoulder blade when I breathe in or sit in certain positions. I went to the doctor and she said it sounds like costochondritis. I don't think it is (now that I have learned about it), because it doesn't hurt to the touch, and I don't feel any swelling or chest pain.
Well for the past couple days I have been experiencing a strange new feeling. I thought it felt like a weird "popping" feeling, but not painful. It is directly below my sternum in my extreme upper abdomen, in between my ribs. I have just been dismissing it, thinking I was just being dramatic. Tonight I was just resting, watching TV, and I put my hand there to feel it, and I noticed that it is my heart beating. It isn't constant. It happens for a few minutes, multiple times per day. And when it does happen, it isn't every single heart beat, it's just some heart beats. It is VERY noticeable, and strong. Noticeable enough to distract me from what I am doing (again, noticeable, not painful). I have never felt this before in my life. I googled the symptoms and kept coming up with aortic aneurysm. I know that googling symptoms is a BAD idea and usually is quite wrong.
Two nights ago I fainted very briefly (a few seconds) for the first time in my life.
Can anyone tell me what this may be? I have another appointment tomorrow, I am just wondering if anyone has any insight...
