I have been diagnosed with gallbladder stones and undergone laparoscopy for removal of gallbladder in may 2019. No major change or pain observed there after. However from the past 20 days, I am experiencing pain in upper abdomen. I have advised endoscopy and some blood tests. Endoscopy test has revealed chronic duodenal ulcer. The blood test serum amylase is 87u/l and serum lipase is 108u/l. Am I suffering from any pancreatic issue or is it just ulcer.
