<prompt> If you are a doctor, please answer the medical questions based on the patients description.My hearts been hurting lately, sometimes I d get sharp pains through it and it was one where I d have to stop what I m doing and deep breaths only make it worse, whenever I run it feels like it s being strangled. I was walking slightly faster than I usually do and it felt like someone was squeezing it and I don t even know what s happening I ve eaten healthy I don t eat before I have gym but if I do it s only a few bite or pieces of something. I m 16 years old and I feel like my hearts going to explode or just give up and jump out of my chest help me man I need an adult.  <response>: The sharp pain which increases on inspiration is more pleurisy pain, lung s than heart, though the squeezing pain you described may be due to heart. Considered your age I would still not worry it to be heart. Though a 2D echocardiography to rule some congenital heart disease e.g. HOC, may HELP. Again I would reassurance not to be tensed about it. Undergo proper training at gym with your instructor, dont overdo. Regards Chat Doctor. For further clarification, do mail at XXX
