What should I do if I feel pain or discomfort?
It's important to note that every once in a while some people may see a small amount of blood coming from the sensor after application. If this happens, you should apply light pressure on the sensor with a tissue – the bleeding should stop within a few minutes.
Minor discomfort, bruising, itching, adhesive irritation, redness, and local infection are possible and have been reported, but are quite rare. Most people will hardly notice the sensor is there!
