Im Chris, 23 yo Male. I have a sharp stitch like pain in my heart / left chest. . It hurts when i breath in. and i get what feels like a prolonged stabbing sensation. I have been having these pains for about 5/6 years, but can go for months without any problem. I can not think of anything that triggers it, or anything that helps the pain. Any info or advice would be much appreciated. Thank You in advance. Chris.
