Dear Mr.Mohan Singh,
Your query--does acid reflux
cause cheat pain----yes, it does.Actually, our oesophagus i.e. foodpipe,is neutral in nature,so any reflux i.e.backflow of acid from the stomach is going to burn the lining of the oesophagus which is very delicate and this causes pain behind the breast bone which we also term as heartburn
,which does not have anything to do with the heart.This can be overcome by consuming cold
milk/icecream etc.,or by taking antacids.Also avoid spicy and sour food when you have this problem.
