Why does it feel like there a burp in my chest, mostly in the middle left part of my chest and what can I do to help this problem ?. Also I got this pain around below my right rids and when I will try to burp I will pat my chest to try n help it come out then I will throw up I'd say stomach acid because I would have bad heartburn after that , why do feel this and what could help?
