Hi.
Thanks for your query.
Read and understood your history and query.
You have nausea for 1 month, a long time to keep you from a proper diagnosis; lost weight, have cramping in the right side under the rib, that is referred to the back, sweating, orange urine in the beginning.
This followed after 1 week with undigested food in the stools and nausea, 3 ER visits,
Hydrocodone increases pain, Urine shows raised
bilirubin, coated tongue, all other tests are normal,.
All the history together shows that there may be a problem of
hepatitis or
cholangitis or Sphincter of Oddi dysfunction.
Sometimes you need to undergo repeat tests as sometimes the tests may not show the problem.
I would advise the following:
Get the full liver profile including GGT, this may give a clue.
Therapeutic trial with an antibiotic and
metronidazole may help to get well.
Avoid food rich in fat and oil.
Get an opinion of hepatobiliary Specialist.
