Hello, Pain in shoulder blades and back can be due to reasons like a muscle spasm, it can be a referred pain because of some other underlying cause, compression of a nerve. You also have mentioned that there is a lot of burping lately, as well as burning sensation in the chest which happens most commonly due to problem of acidity. Whenever a patient comes to me with symptoms like this after excluding cardiac issues and other possibilities as a reason behind it, I suggest them taking antacids like pantoprazole empty stomach early in the morning which provide pretty good relief. Also its better to avoid foods that cause acidity. Drink plenty of water too. There can be any other cause but to exclude other causes my advice to you see a doctor and give a detailed history to him. Once the underlying cause is known you will be given appropriate medical treatment by your doctor. Hope I have answered your query. Let me know if I can assist you further.
