I am having trouble in my lungs and heart area. It hurts to breath in. It gives me sharp pains right were my heart is. It is hurting right now and sometimes it feels like something is pressing against my heart and making it feel like there is pressure on it, it stays constant for a few minutes. Also feeling brused. Is there a doctor or someone can tell me a little bit of what the problem might be?? Im worried because i am only 17 and i am having problems.
