Thanks for your query.
The pain in upper stomach can be caused by many conditions. The burning or tearing type of pain that radiates to the back can be caused by some conditions like duodenal ulcer
, gastric ulcer, pancreatitis
To rule out these conditions a physical examination and some investigations need to be done. Investigations can include some blood tests, serology for bacteria named H. Pylori, Ultrasonography
of the abdomen, etc. A trial of medicines meant to treat ulcers of stomach can also be taken.
can be ruled out by conducting some blood tests like serology for gluten
and gliaden components of diet.
Hope I have answered your query.
