I m a 16 year old and I have been to a doc, but I m having some pains in my chest for the past month, and very bad indigestion, I am athletic, but lately when I work out I feel fatigue and weak. I also have a lot of pressure when I bend over. I m scared. But the doc says it could be stress and I have a small murmur, but he did and EKG and X-ray which both showed to be fine
