Never use the same finger back to back.
For starters, using the same finger day after day leads to callusing, which means thicker skin. This thicker skin makes it harder to prick the finger. Switch it up as much as you can with new fingers.
Test on warm, not cold hands.
If you live in true wintertime climates, you know the feeling of cleaning the snow off your car without gloves to protect your hands. Yes, it’s painful. Now, imagine pricking your finger right after that – even more painful. Thus, it’s always better to stick your fingers when your hands are warm. Also, warm hands get the blood circulating well enough for a good blood drop during the prick.
Try the sides.
It’s common practice to stick the tip of the finger during blood sugar testing. Though, that’s possibly one of the most sensitive parts of the body. Try pricking the sides of your finger. It may hurt much less.
