I actually get heart palpitations, too... but it's rarely painful. Just disconcerting when it feels like your heart is trying to jump out of your chest. Sometimes after some heavy toking (I also smoke cigarettes... ), I get a bit of tightness in my chest. Oddly enough, on the left side. But after several x-rays and checkups, I've been deemed healthy.

Definitely get checked out by a doctor as soon as you're able to. You sound to have an active, healthy lifestyle... so hopefully it's nothing to worry about. But it's still better to be safe than sorry.

Take care. :jointsmile:
