Suggest Treatment For Symptoms Of Chronic Pancreatitis
Chronic pancreatitis is the most probable reason.
Thank you for the query.
What was the reason of pancreas tail removal? Was it a chronic pancreatitis or tumor? If it was a tumor, was it malignant or benign?
Your symptoms are very characteristic for chronic pancreas inflammation. No doubt in that. To diagnose it, you should have abdominal CT rather than an ultrasound which can only poorly visualize pancreas.
Hope this helps.
Bile ducts obstruction should be ruled out as well.
Have you had liver enzymes and pancreas enzymes checked? As another thing to be ruled out is bile ducts obstruction. In case of that issue ERCP should be done.
