Thank you for the query.
To diagnose peptic ulcer
, gastroscopy is necessary. Moreover, symptoms described by you are not characteristic for peptic ulcer. More probable are gallstones or rib nerves pain.
Gallstones usually give upper right abdominal pain
which radiates to the back. Symptoms are triggered by fatty food or alcohol. Nausea
is very often present.
Rib nerve pain
gives sharp needle-like pain. It aggravates when moving the chest (breathing) and can be unnoticeable when not breathing.
If gallstones seems most probable, ultrasound
should be done. If rib nerve pain seems more possible, you should try Diclophenac 50 mg twice a day (should be taken with Omeprasole 20 mg once a day to protect your stomach)
Hope this will help.
