Hello, I'm 23/about 10 pounds overweight/normal blood pressure/no family history/general good health/no prior heart trouble. Recently during a fever exam a mild murmur was found. I was asked to return after the fever so they could monitor it and they found that there was no longer a murmur. A follow up exam a month later also found no murmur. I work out regularly and used to play professional soccer without any trouble in the past. Blood tests (twice in last 6 months) came out normal.
My problem is this : I occasionally feel a mild pain on the left side of my chest, its never so high as to be noticeable and does not radiate. The doctor dismissed it as a panic reaction. I am not too sure myself if I'm imagining it. I still play regularly (sometimes violently) without any shortness of breath or anything like that. But this pain keep lingering on my mind and the irritating part of it is I'm not sure if its there. Should I see another doctor about this ?
