Your questions,
answered.
Practical information to help you take the next step with confidence.
Do I need a referral?
Self-referrals and referrals from GPs or other specialists are welcome. If you are using private medical insurance, check whether your insurer requires a referral and obtain authorisation before booking.
Will I necessarily need surgery?
No. The first step is to understand the diagnosis. Your plan may include observation, rehabilitation, pain management, investigations or surgery, depending on your condition and goals.
Can I have a virtual consultation?
Yes. Virtual consultations are available for suitable discussions and follow-up. A face-to-face examination may still be necessary before a diagnosis or treatment plan can be confirmed.
What should I bring to my appointment?
Bring relevant clinic letters, scan reports and images, nerve test results, your medication list and a short timeline of symptoms. Ask the practice how to share medical records securely.
