About an hour ago I had an unpleasant feeling in my chest accompanied by tooth pain at the top of my mouth only. I have barretts esophagus and take Aciphex daily. My stomach felt fine but I did have several cups of coffee this morning. I am 40 and in good health, I think.
Thanks for your question on Chat Doctor. I can understand your concern. Possibility of acid reflux related chest discomfort is more. But better to first rule out heart related diseases because these can cause unpleasant sensations in chest. So get done ECG and 2d echo. If both of them are normal then no need to worry about heart diseases. You already have Barrett s esophagus. So you are at risk of reflux disease. You had 2 cups of coffee this morning. Coffee contains caffeine and caffeine is the risk factor for acid reflux. So better to avoid excess coffee intake. Continue antacid Chat Doctor.  Avoid stress and tension, be relaxed and calm. Avoid hot and spicy food. Don't worry, you will be alright. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
