When first installing the sensor, slight discomfort is not unusual and can occur if you are nervous about the process. When following the installation process step by step, our customers usually find that any sensations should disappear in a few moments. Carry on with your day as normal, and if you feel like the pain is too much, do reach out to us so we. can see what can be done.
If you have inserted the sensor other than in the back of your arm, we are unable to give advice on possible sensations or reading inaccuracies.
