Chest Pain Anyone?

I sometimes have chest pain around my heart that feels like a stabbing pain, lasting only a few seconds, and happens a few times an hour and for several hours. It doesn't happen every day but maybe once or twice a week. This has been happening for about two years, with a few months where it didn't happen at all. I had an EKG and echocardiogram which showed that I have a leaky valve and the beginnings of an aortic anyeurism. They cardiologist told me my results were normal. They said I could come back in a year for a check up "if I wanted to". I don't consider that normal. I wouldn't even have known the results of the echo had I not gone to the patient portal and looked at the findings myself. This is only one incident of many in the last 2 or 3 years in which a doctor or nurse missed important things. My blood pressure and cholesterol levels were dangerously high for at least a year and no one said anything about it. When I saw my records on the portal and saw they were so high I had to ask for medicine. I know that having uncontrolled high blood pressure for a long time can cause some serious harm. That was the first time I had used the patient portal and looked at my records. Now I do it every time I see the doctor or have a test because they make mistakes and miss things often- it's scary. It's important to be involved in your own medical care because you just can't trust your life to anyone else.
Anyway, I am having those chest pains now and I was just curious to know if anyone else experiences random chest pain that comes and goes?

While on the subject of my chest, does anyone ever have pain around their breast implants? Could my immune system be attacking the implants? They have been there for about 10 years.
