Be seen today
Seek same-day urgent medical care for a persistent fever with pain under the right ribs, especially if you also have chills, vomiting, jaundice, or a recent abdominal or bile duct procedure.
These symptoms have several possible causes, but they need assessment.
If you are already being treated, contact your care team promptly if fever or pain returns, a drainage tube stops working or comes out, or there is increasing redness, swelling, or leakage around the tube.
Every sign above is quoted from the sofidex article on Pyogenic liver abscess. If you are not sure, err upward — it is always reasonable to be checked.
