It could be natures way to tell you to slow down.

It's never bad to just get checked out.

About 8 years ago I was working on some computers and smoked a few joints of swag and a pack of cig's. I got agravated and my heart beat got fast then my arm hurt some. No chest pains. Then my heart fluttered. Jump in the car and had my wife drive. She didn't know anything except I was feeling bad.
Walked in the hospital and went right to the back where they found I was having a heart attack. Well seems I had some small blockage that I could of taken care of with meds the next year. However they seems to think I needed something more.

Now I owe 100 thousand in med bills because they scared me into what they wanted to do.

So now I worry cause no job and my families in debt that I can never pay.
What's the answer. Jack me up on a bunch of thier pills and that makes it better.

Moral of the story is Just take care of yourself.
