Hi.
Thanks for your query.
Noted your history of dull pain below the right
rib cage wherein the tenderness is localized around the belly button and up the right side. There is also night headache around your eyes.
Since the pain is under the rib cage but palpation shows tenderness near
umbilicus, the chances are that it may be more of a colitis or intestinal pathology.
Get the HIDA scan but if it is normal go for the following investigations also:
Stool test for 3 consecutive days.
CT scan of the abdomen with enteroclysis.
Tests of thyroid functions.
A clinical trial with a course of an antibiotic and
metronidazole, probiotics too or as per the tests reports.
And dewormin medicines.
I hop[e this should help you to get a relief, get the diagnosis and plan for a proper treatment.
Gall bladder or sphincter of oddi function is a rare condition.
