A CGM sensor is designed to be pain-free, so if you experience any discomfort, irritation, or unusual symptoms, follow these steps:


1. Remove the Sensor Immediately

⚠️ If you feel pain, itching, or notice redness, swelling, or bleeding, remove the sensor right away.


2. Assess the Affected Area

🔍 Check for signs of irritation, such as:

  • Redness or swelling

  • Persistent pain or discomfort

  • Skin irritation or an allergic reaction

If any of these symptoms persist, consult your GP or healthcare provider.


3. Before Applying a New Sensor

💡 We recommend consulting your GP before applying another CGM sensor, especially if you experienced:

  • Skin irritation or sensitivity to the adhesive

  • Pain or discomfort beyond mild sensitivity

  • Bleeding upon removal

Consult Your Doctor Before Starting: If you have a history of sensitivity to adhesives, such as reactions to plasters or Band-Aids, discuss this with your healthcare professional before starting the Vively CGM program. They can advise whether the CGM is suitable for you and suggest ways to minimize irritation.

Alternatively, you can explore options like:


✔️ Rotating sensor placement to a different area on the back of the arm
✔️ Ensuring clean, dry skin before application


Final Thoughts

If your CGM sensor is causing discomfort, remove it immediately and assess the affected area. Always prioritise your comfort and safety, and consult a healthcare professional before reapplying a new sensor.
