When is a second opinion useful?
- Symptoms such as weakness, numbness, imbalance or memory change that remain unexplained
- Treatment that has not helped as expected
- An MRI or CT report with findings that are hard to understand or that differ between reports
- A serious diagnosis, before starting long-term treatment
- Advice to undergo surgery or an endovascular procedure, such as aneurysm treatment or stenting
A second opinion is a planned outpatient review. Sudden weakness, speech difficulty or a sudden severe headache is an emergency: call 108.
