Is any of this happening?
Be seen today
Seek urgent medical advice if you have a known or suspected pheochromocytoma and develop repeated severe symptoms, very high blood pressure readings, or a new irregular heartbeat.
3
Does any of this apply?
Book an appointment
Arrange a routine medical appointment if you have repeated episodes of headache, sweating, and a pounding heartbeat, especially if blood pressure is high during the episodes.
These symptoms have many possible causes, so they need assessment rather than self-diagnosis.
If you have been treated for pheochromocytoma, contact your follow-up team about returning spells, new persistent pain, unexplained weight loss, or changes in blood pressure.
These symptoms do not necessarily mean the tumor has returned, but they should be reviewed.
Every sign above is quoted from the sofidex article on Pheochromocytoma. If you are not sure, err upward — it is always reasonable to be checked.
