You seem to be suffering from an upper abdominal problem , pancreatiti as derscribed by you . You have not mentioned about the surgery that was done , pancreatic necrosectomy is done for pancreatic necrosis
, pancreatic stone is removed by ERCP & stenting.
Please clarify your operation. In the meantime let me tell you that the medicines you have mentioned are harmful as they induce spasm in the pancreatic duct
. AVOID them
