Call emergency services for a seizure, severe muscle spasms, breathing difficulty, collapse, or sudden confusion.
These symptoms have many possible causes and should not be assessed at home.
Seek prompt medical advice if you have already been diagnosed and your pain is getting worse, you develop new cramps or tingling, or treatment is causing nausea, unusual thirst, frequent urination, or constipation.

Seek urgent medical care after a fall or injury if you have severe bone pain, visible deformity, or cannot use a limb normally.
Sudden pain without a clear injury may also need urgent assessment because weakened bone can fracture during ordinary activity.
Arrange a routine medical appointment if you have persistent bone pain, unexplained muscle weakness, increasing difficulty climbing stairs, or a change in how you walk.

Every sign above is quoted from the sofidex article on Osteomalacia. If you are not sure, err upward — it is always reasonable to be checked.
