Thank you for the query.
Yes, this sounds like an peptic ulcer
. Its quite common that what seems to be gallstones pain after its removal turns into peptic ulcer pain. That is why you probably havent noticed any relief after surgery.
If the pain radiates to the back, stones in the bile ducts are also possible. Due to this issue, stool can get white, urine dark. Nausea
It is advisable for you to have abdominal ultrasound
first. If no stones will be present, gastroscopy should be next step.
In a meanwhile please avoid fatty foods, spicy foods, coffee, alcohol.
Hope this will help.
