Thank you for the query.
Yes, it can be a food poisoning
. However your symptoms can be also caused by gallstones in the bile ducts. Upper right abdominal pain
which radiates to the back, nausea and itching (due to jaundice) are very characteristic symptoms of this condition. Nausea, vomiting, pale stools, dark urine can also appear.
Food poisoning usually causes diarrhea, vomiting and fever.
Other possible reason of your symptoms is urinary tract infection
, urinary tract stones. With this condition you should have frequent urinating, burning while urinating. Blood in the urine can also appear.
I suggest you to visit your doctor and have abdominal ultrasound
, blood work, urine analysis, liver tests (AST,ALT,GGTP,AP), bilirubin
, amylase, urine amylase.
Hope this will help.
