Hi,
I'm sorry you're not feeling well. It's always best when you have chest pains to have your heart checked out. It could be anxiety, but it could also be gas/or heartburn. I get acid reflux occasionally and I've had crushing (feels like heart) pains in my chest, so bad that I can barely breathe for a good 5 min. The gas can cause an air bubble in the diaphram muscle and it hurts like hell. I hope it's nothing serious like your heart. Take care.
