Thank you for the query.
Such symptoms may be caused by gallstones(most probable), acute pancreatitis
, peptic ulcer
, urinary tract
stones. With such symptoms you should have abdominal ultrasound
and full blood work with liver tests (AST,ALT,GGTP), amylase, bilirubin
and urine analysis. It should be done as soon as possible as with such symptoms there is a risk of bile ducts blockage due to gallstones what can lead to acute pancreatitis. Especially if you have noticed that your urine is dark, stool is whitish or the skin is itching. Until this test are performed, you should prevent most of the foods especially if food aggravates your symptoms and drink water or tea.
If mentioned conditions ruled out, you should get scheduled for upper GI endoscopy to have stomach checked.
Hope this will help.
