I have been experiencing pain behind my belly button for numerous months now. Urologist stated my bladder was emptied out but ultrasound close to belly button showed fullness. I have had a couple bacterial infections and treated with antiobiotics, diagosed with hiatal hernia with an MRI. Ruled out apendicitis but have not seen a gastronologist yet (no insurance). I have been taking omeporazole for some time now but today I am experiencing severe pain in my stomach (behind belly button)after taking one. what should I do?
