Heart issue, kind of long but please read

[SeasonsDecay]

Not even sure where to start. Okay I am 26 years old, I have always had a slight anxiety problem-which i'm not on medication for. I feel like I know the difference between increased heart rate due to anxiety, and this heart issue i've been having. The past 2 years or so it has become an issue that i've just been dealing with and planning my life around..and i'm so sick of it. My symptoms and very many and random and i'm not even sure they are connected w/each other.
I'm definitely sensitive to caffeine- at least sometimes. What's funny is I can have a cup in the morning at work and i'm fine, but if I have one home or in the car on the weekend going somewhere, my heart pounds. Strange- but it's true.
My heart pounds after meals- sometimes - and I do notice that USUALLY it's a carby meal-but not always. What I have noticed? Is that while my heart is pounding and feeling uncomfortable, I can't have a seat belt on, a tight shirt on, sometimes I even take my bra off.. because it feels so constricting. I also notice that if I go 'number 2' it makes my pounding heart sometimes ease up.. like a release of some kind? I don't know.
Alcohol helps - usually. But the next day after too much drinking..it's bad.
Heat makes it worse. And it's not always that my heart is going super fast, but it's definitely a faster rate than normal, and it just FEELS like it's pounding and it's very uncomfortable and limits what I can do while it's doing it.
This is also another strange thing....when i'm on the treadmill at the gym, i'm usually okay. I can walk, put the treadmill on the slope and go to town. If I go for a walk around my neighborhood and there's a hill..my heart pounds out of my chest when I walk up it and I get shortness of breath. It has come to the point where I avoid walking where there's hills. Once again..usually if I have a few beers, I don't have that issue.
I have gone to the doctor for palpitations (I also get skipped beats..but that's another story and I know that's more anxiety based rather than this specific heart 'issue) and all they really did was listen to my heart and say it sounded fine. I have no insurance at this point, so I can't just make an appt with the doctor.
Does anyone have ANY thoughts/advice/ANYTHING??! Please help!

Hi,

I'll try to give you a good answer.

The first thing you should get examined is your thyroid levels. I can't say for sure, none of us are doctors here, but if your symptoms should indicate a disease, hyperthyreoidism was the only thing I could think of.

There is also a condition where your body produces too much insuline after a high-carb meal. This is not a disease pr say, more of a condition where you should avoid too much sugar and white bread. Your blood sugar levels drops too quick, putting your body in an "alarm" state, where you produce too much adrenaline and get palpitations.

Both conditions can easily be ruled out or confirmed by a general physician.

In general, your symptoms seems a bit like anxiety reactions. They can occur even if you're not aware of them. Especially the point with exercise outdoor causing palpitations is very common and a classical anxiety syndrome. I have the same problem. I could exercise on a threadmill or a bike as much as I wanted, but as soon as I started climbing hills, I got palpitations. It resolved by "counting backwards" as I walked up the hills. You should try that :)

The palpitations after eating can have the same cause. Have you read about the "Pavlov's dog experiment"? If not, google it. It's not always easy to understand how our subconcious mind works :)

It's possible a small amount of beta blockers, along with some reassurance, would be of great help to you. I would advice you see a doctor when you are able to, get thyroid levels checked, and ask for a small dosage of beta blockers, and an explaination of your symptoms. It helped me a lot!
