Hello
I share your concern.
Cramping in between the shoulder blades and burning sensation in the center of chest is a matter of concern.
Since you haven't mentioned about your age, if you're more than 40 and susceptible for
heart disease than it might be related to heart disorder like angina and it warrants urgent medical care.
At young age it might be related to gastrointestinal disorder like GERD,
hiatus hernia, acid reflux or oesophagitis.
I would advise you to take Antiacidity medicine like
pantoprazole or ranitidine group of drugs with antacids for 4-5days, if it doesn't help than I would advise you to
consult gastroenterologist for an ultrasound and upper gastrointestinal endoscopy if need be.
Meanwhile you should avoid smoking and drinking as well as Fatty fried spicy and junk food and carbonated beverages.
Have lots of fresh fruits and vegetables with
dietary fiber supplement.
Hope you will find my answer informative and useful please feel free to ask for further assistance I will be happy to help you.
Best wishes
