<s>[INST] This is odd.  52yr female.  on average 1 drink a week.  no prior symptoms/history.  no meds.  I get chest pain after the first sip of liquor.  cheap booze.  top shelf booze presents no symptoms.  I now watch the bartender to make sure.  I know it is not the alcohol, so it must be something that is removed in the process between cheap and premium liquor.  Any ideas what the trigger might be????? [/INST] Thanks for your question on Chat Doctor. I can understand your concern. Since you are regularly taking alcohol, in my opinion, your chest pain is mostly due to gastritis. But better to get done ECG and 2d echo first to rule out heart diseases. If both are normal then no need to worry about heart diseases. No matter whether it is cheap or premium liquor, gastritis is bound to occur with regular use of alcohol. So better to avoid alcohol. Avoid hot and spicy food. Avoid junk food. Avoid large meals, instead take frequent small meals. Start proton pump inhibitors. Avoid stress and tension, be relaxed and calm. Don't worry, you will mostly improve with all these. Hope I have solved your query. Wish you good health. Thanks. </s>
