Is any of this happening?
Be seen today
Seek prompt medical advice for symptoms that could indicate a kidney stone, such as strong pain in the side or back, blood in the urine, pain when urinating, or repeated vomiting.
These symptoms do not prove that calcium is dangerously high, but they need urgent assessment.

Does any of this apply?
Book an appointment

These symptoms may have many causes, but they can justify checking calcium and reviewing bone health.
Every sign above is quoted from the sofidex article on Jansen disease. If you are not sure, err upward — it is always reasonable to be checked.
