Im 19, 5 foot 9, 230, and Ive been having a suspitious feeling over and around my heart.  It is like a sliget tightness on the lower inside of my breast, right over the heart, and sometimes Ill get a sharp pain under my left arm, about leval with the heart, maybe a little lower.  Also, at times I can feel my heart beeting in my chest, and my neck and my head, usualy when Im laying down.  I also have at time bad cases of heartburn, although usualy when I have an empty stomach. I know that at my last appointment with the Dr, my blood pressure was up a little bit, but nothing too bad.  I have put on more weight since then though, and I have a pretty poor diet, almost no vegiez or fruits, although Im trying to change that now, and I dont excersize. Also, I have been on aderall since I was 7 for ADHD, but I stopped for almost the past year because I didnt think I needed it.  Now when I take it, it makes my heart pound more, and the tightness seems more prevolent.  What is this Tightness over my heart and is it something I should be concerned about?
Thanks for your question on Chat Doctor. I can understand your concern. At your age (19 years), heart diseases are not mucChatDoctormon. But your symptoms are more suggestive of heart disease. And you also had slightly elevated blood pressure. So first consult cardiologist and get done blood pressure monitoring, ECG, 2d echo and stress test. If all these are normal then no need to worry about heart diseases. Sometimes stress, anxiety can also cause similar symptoms. So avoid stress and tension, be relaxed and calm. Try to lose weight and stay fit. Avoid junk food. Do regular exercise. Don't worry, you will be alright. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
