Hi there. I am 27 years old. For several years now (about 5) I have had a dull, mild, uncomfortable left chest pain . Not associated with exercise. But pretty constant. Also, a pain in my left wrist . I went a few years ago to the docs and had an EKG and it was apparently normal. Although I was only hooked up to it for like 1 minute. I was told I had a heart murmer the first time I went. Then, apparently, the next time I went I didnt. Should I go back and request a full investigation by a cardiologist? I honestly do think my body is trying to tell me I have a heart problem. What do you think? Thank you Doctor.
