I woke up yesterday with heavyness of chest, throughout day and since I keep getting a tightening, which is painful and diff to breath - it eases but dull pain remains.... am now getting tingling in right arm down to hand - had put it down to wind as have been burping but not sure now ?
Thanks for your question on Chat Doctor. In my opinion you are having HERD mostly. But better to rule out cardiac cause first for your symptoms. You're all symptoms like chest tightness, heaviness, difficulty in breathing and radiation of pain in arm can be seen in cardiac cause. So get done 1. Ecg2. 2d echoic both are negative, then no need to worry much for cardiac cause. You are having mostly HERD (gastroesophageal reflux disease). Burping can be due to HERD. So better to avoid hot and spicy food.  Avoid stress and tension. Avoid large meals, instead take frequent small meals. Start Proton pump inhibitors. Don't worry, you will be alright.
