Is any of this happening?
Be seen today
Seek prompt medical advice if pain follows a significant injury, or if you develop fever, visible swelling, unexplained weight loss, persistent vomiting, or worsening abdominal symptoms.
These features are not typical of uncomplicated slipping rib syndrome and may need a different evaluation.

Does any of this apply?
Book an appointment
Arrange a routine medical appointment if you have recurring pain, clicking, or tenderness near the lower ribs.
Assessment is especially useful if symptoms limit movement, disturb sleep, or continue despite simple self-care.
The article also says
Do not assume sudden chest or upper abdominal pain is caused by a slipping rib, even if you have had similar pain before.
Every sign above is quoted from the sofidex article on Slipping rib syndrome. If you are not sure, err upward — it is always reasonable to be checked.
