Hey, so I've been having pains in my chest (between breasts and traveling pain to left shoulder) when ever I eat or drink (at first it felt like something was there now it feels like a burning pressure). The pain does vary every single time. it started about three weeks ago before I went on my trip to England (still here for a another three weeks). Recently I've been burping a lot (not sure if I'm forcing it for concern) and sometimes (happened like 3 times) a foul tasting yellow liquid will come out. If this still happens when I get back home in will go to the doctors l, but should o be worried now and what might it be?
