Thank you for the query.
Your symptoms sound like caused by heart problem - heart ischeamic disease or even heart attack
. This is the first thing which should be ruled out. Heart ECG and heart enzymes (CK-MB and Troponine) should be performed. Heart ultrasound
might be necessary as well.
If no heart problems found, you should have upper GI endoscopy performed as such symptoms may appear with gastric reflux
disease, peptic ulcer
. Reflux disease is very often associated with asthma what can be the reason of breathing difficulty. To diagnose it, blow test should be performed (spirometry
If no findings in all this tests, abdominal ultrasound, full blood work, liver tests (AST,AT,GGTP) and amylase, bilirubin, urine analysis should be performed.
Hope this will help.
