Hello! Considering that I am 19 years of age, I have been experiencing severe sharp chest pain for about a year and a half now! This pain just feels like a heart attack but not, obviously. It is very sharp along with shortness of breath, heart burn, and pain when I breath in deeply, move my left arm up and even when I tilt my head up/down/ sideways, and stretch. Sometime when I want to lay down, it would bother me too. I have consulted with my doctor and simply perscribed me acid reflux suppression since this is something I have since a child but I don t believe this is the problem. I have my thoughts on certain things it might be but then again I am not the doctor ☺️ What should I do, should I be deeply concerned do these symptoms mean anything serious?
