About a month ago I was having this weird chest pain/burning sensation off and on for about a week, finally went to the doctor, they didn't know what it could it be so they sent me to the hospital. waited there for a while, got tests done, they had no idea. Said it was probably acid reflux, which i've never had an issue with before. After i got it checked out i was watching my diet, cut back a lot on smoking cigarettes and drinking coffee (all things they said could trigger it) it went away for a bit and now occasionally flairs up, it's super weird and sucks.
