It is been 2 days continuously I'm experiencing burning sensation throughout my chest & stomach throughout the day almost & mild acidity also; it is very difficult to handle as I don't know what is wrong & how to get relief from this  I'm having burp & heavy feeling continuously. Most frequently I experience gas, burping & acidity. After meal sometimes I feel stomach & chest heaviness & mild pain. I have allergic rhinitis, other than that do not have any issue. Also I get acnes a lot since last 1.5 years & my face skin has become super oily, alongside dandruff issue is an add-on. I stay away alone for my work & eating schedule is irregular & I have to eat outside food. I used to smoke sometimes but I have stopped it now. Please guide me.
