Hi and welcomet to HCM.
Have you ever considered stomach issue. This sounds like gastritis
,gerd or hiatus hernia
. You should do gastroscopy to evaluate this. Gallbladder
may cause such symptoms too. But if they dont see stones or polyps I dooubt this is causing your symptoms. You should also do CT scan, there might be cyst in spleen, liver or pancreas
which can press your digestive system. If your symptoms persist you shouldnt ignore it and you should insist on those diagnostic tests.
Wish you good health.
