<s>[INST] Hi, my dad has been feeling an uncomfortable feeling in his chest. This is going to sound bad but we had White Castle s for dinner. He said he has never felt like this before so we don t know what to do. He has had some tums and some pop but that didn t help either. Please help [/INST] Thanks for your question on Chat Doctor. I can understand your problem. In my opinion, your father is having acute gastritis mostly due to eating. But it is better to rule out cardiac cause first. So get done ECG. If ECG is normal then no need to worry much for cardiac cause. It is mostly acute gastritis. Ask him to follow these steps for better symptomatic relief.1. Avoid hot and spicy food.2. Avoid stress and anxiety.3. Avoid large meals, Instead take frequent small meals.4. Take proton pump inhibitor.Don't worry, he will be alright. </s>
