Answer:
You could have some inflammation in your chest that is causing the discomfort. Its possible you bruised a muscle and didnt realize it. The best thing to do would really be to get things checked out. You can never be too safe, and perhaps the pain is continuing because you're focused on it. Get it checked out.
You should go to our doctor if it doesn't get better soon. That could be a lot of things. My first thought is GERDs or gall bladder since you don't think it could be your heart. Another possibility could be bronchitis and/or sinusitis. This is a rare one, but if you have endometrioses it could be related to that.
YOU NEED TO GO TO THE DOCTOR. it could be something with your heart.
