A week ago I woke up in the middle of the night with shortness of breath. I was pale, sweating, and a bit dizzy. I didn't feel chest "pain", just an intense pressure. I went to the ER, and :
- blood pressure was fine
- ECG was fine
- chest x-ray was fine
- blood tests (3 over 9 hours) were all fine
I was sent home, but the chest was store sore all day. Yesterday I went to the cardiologist and I did an ultrasound of the heart, which came back ok too, other than a small area which the cardiologist said that he couldn't quite make out, so I may have to re-do it, he's not sure yet. In about a month I'm going to get a 48 hour holter, and I'm being sent for a CT angiogram in 6 weeks.
Another thing of note is that I've been having trouble sleeping. When I close my eyes, my pressure seems to intensify and I get this sensation of being "out of body". I ca't explain it. It's like I try and take a deep breath, but I don't feel the release of breath out (although I obviously do, or I'd be dead). The pressure is constant now. During my initial episode, it was about a 9/10... right now, it's about a 3.
I do have a family history of health issues - my dad had a heart attack - but with all of my tests coming back negative (so far), could this just be stress? Anxiety? Or something else entirely?
Thanks for any help you can give.
