Heart related chest pain

Can someone please describe to me what chest pain feels like when its due to your heart. For some time now i have been experiencing chest pains. Most sharp and short lived, some dull and lasting a while. I am pretty scared theres something wrong with my heart and im only 22. It's consuming most of my thoughts every day and i cant do anything about it because i have no health insurance. Though 2 years ago i had an echocardiagram done and it all came out ok. Please any help would be appreciated

The chest pain (angina) and discomfort common with angina may be described as pressure, squeezing, fullness or pain in the center of your chest. Some people with angina symptoms describe angina as feeling like a vise is squeezing their chest, or feeling like a heavy weight has been placed on their chest. This pressure can extend to the arm, especially the left arm, neck, jaw, shoulder or back.

Stable angina means the symptoms occur with physical exertion or stress, and unstable angina occurs with or without exertion.

A couple of weeks ago I was sitting at my computer and all of a sudden I had burning pain in the middle of my back. Then it felt like I had eaten way to much of a Thanksgiving meal. There was pain in my lower jaw on both sides. Did I have a heart attack? I had a similar episode a few months back.

From what I can gather, there is no steadfast rule to what you feel with regards to heart attacks. Some people actually dont even know they've had one. The other end of the scale is people are doubled up on the floor in agony. I had several of these over a period of three days and they only occurred if I ate something. Of course I assumed it was severe indigestion. I remember being on my knees clutching my chest begging god to take the pain away. The episodes lasted about 15-20 minutes each time. On the last episode I actually vomitted from the pain and then decided to go to the hospital. It's a good job I did. I will never forget those pains as long as I live and in my case they were very intense. If you imagine gastoenteritis, multiply the pain by 10, you are close to how it felt each time. The strangest thing that I remember is that the slower I breathed, the quicker the pains disappeared. Quite the opposite to what you would expect.
