No. Applying the blood sugar sensor shouldn’t hurt at all.
The sensor contains a small filament, and during application, this goes into the fleshy part of your upper arm. You may feel a small pinch or a light tingling sensation.
Because the filament enters your bloodstream in order to collect your blood sugar data, you may see a small amount of blood in the center of the sensor. This is completely normal so don't worry.
If the application process was painful, please reach out and contact our support team. If you need to remove your sensor, please do not discard it — Add the sensor to the clamshell in your 'Blood sugar sensor & reader return' box to be sent back to us at the end of the testing period.
