[|Human|] When I have caffeine, say a cup of coffee or a coke, I get chest pains, my chest feels tight and it feels like my breathing is constricted. I have never had this problem before, and have always been able to drink caffeinated beverages until this April. What is causing this?
[|AI|]  Hello dear, thanks for your question on Chat Doctor. I can understand your situation and problem. In my opinion you are having mostly HERD (gastroesophageal reflux disease).  Caffeine containing Chat Doctor.  It actually causes laxity of gastroesophageal sphincter.  Because of this the acid of the stomach tends to come up in the esophagus and cause the symptoms like chest pain and tightness. So better to start Proton pump inhibitors. Avoid coffee for few days. Avoid stress and tension. Don't worry, you will be alright.
