Im 22 year old male. I have been having chest pain on the left side of my body kinda underneath my armpit and in my heart area and it has caused anxiety. My stool has been green light green. i seen a cardiologist and my hearts fine. I dont smoke. i was told nothing so far by my doctor my ths came back normal everything normal. I have been burning a lot and sometimes it relieved the pain. Its been going on for a month now.
