Hi. I've had some problems with shortness of breath from when I was a teen (I'm 31 now). People will often ask why I'm sighing (they'll think I'm annoyed or bored) but I'm really just trying to take a deep breath and having no luck. It feels like I'll inhale and then it'll catch and I can't inhale any deeper. Sometimes I can exhale all the way, really push everything out and, then, when I inhale I can get enough air in.
At the same time my heart does wacky stuff, it'll speed up for no reason, slow down for no reason and will also just be generally weird - almost like it's skipping beats or out of rhythm. Sometimes it feels like someone has squeezed around the center of it and the top and bottom are beating funky. I had a holter monitor and EKG when I was late teens, very early 20s and they said I had a minor heart murmur (murphy's law, my heart behaved during those tests).
Anyway, when I hit about 25 it started getting worse. I have times where I've gotten dizzy from not being able to get a deep breath and my heart beats irregularly almost every day now. It's especially bad when I'm laying down, once it sped up so fast you'd have thought I was fleeing a serial killer through the woods and another time it slowed all the way down and began beating so slow there were pauses of up to five to ten seconds between a few of the beats.
I keep thinking if I go to the doctor he'll just say I'm overreacting, or I'm a hypochondriac or he can't find anything wrong and then it'll be a giant waste of time and money. Other times, when I can barely breathe or when it feels like my heart is about to stop, I get really scared but THEN I think, well, it's been like this since I was 16 and now I'm 31 and, sure it's gotten worse, but it can't be that bad when it's lasted so long, right?
So, to wrap up THAT long winded explanation, does it sound like something I should go back to the doctor for (even though I went when I was 16 and they really didn't find anything other than the mild heart murmur) or just ignore it?
Heart disease does run in my family - my mother has a severe heart murmur and my Uncle (who is 50 and in excellent physical shape) just had a heart attack and had to get a double bypass.
I don't know if it matters but I have really low blood pressure, especially in the morning. I also have very mild hypothyrodisim and am on the lowest possible dose of levothyroxin for it. Other than that I have no health problems and am on no other medication.
