Is any of this happening?
Be seen today
Seek urgent medical care for:
Severe or persistent pain in your side, back, or abdomen
Fever, chills, or feeling unwell with urinary symptoms
Repeated vomiting or an inability to keep fluids down
Passing much less urine than usual
Blood clots in the urine or heavy visible bleeding
This needs urgent assessment because urine may not be able to drain normally.
3
Does any of this apply?
Book an appointment
Arrange a routine appointment if you have ongoing urinary symptoms, repeated kidney stones, visible blood in your urine, increased thirst and urination, or questions about medicines and supplements.
If nephrocalcinosis was found incidentally, follow-up is still important even when you feel well.
The article also says
Fever with severe flank pain can mean a kidney infection combined with urinary blockage.
Every sign above is quoted from the sofidex article on Nephrocalcinosis. If you are not sure, err upward — it is always reasonable to be checked.
