Hello, Thanks for writing to Health Care magic, I am Dr , Muhammad Ahmad , I have read your question closely, I understand your concern and will be helping you with your health related problem. Your problem doesn t seem to be heart or gall bladder, it seems to be caused by Stomach/gut upset,here i need to mention that duodenal irritation does get referred to back and shoulder blades, and it may present with pain not always as burning. it needs life style modification before any medication , here is what you need to do. 1) Avoid coffee, caffeine, Fizzy drinks , junk food, smoking, alcohol (What ever is relevant). 2) Take small multiple meals instead of few larger ones. 3) Drink much fluids. 4) Use fruits and vegetables more than meat. 5) Use fiber diet like fruits vegetables whole grain bread and fiber supplements if needed. 6) Stay physically active. 7) If you are over weight reduce it. 8) After trying out all these measure you can use syrup Gaviscon thrice a day this will keep a check at your gut PH. This all being said, i would like to say that such pain is happening once doesn t cause any alarm but if it keeps happening then you should contact your doctor regarding that. I hope this answered your question, If you have more queries I am happy to answer you. Regards. Dr.Muhammad Ahmad
