I alternate which fingers to poke, but even alternating them I still get very sore fingers..I poke mainly the sides and the tips. I sometimes poke the middle of the pad, I do this if I need a lot of blood. Is there anything I can put on my fingers to alleviate the soreness? I have tried my arms as sites and the difference between the arm and the finger is about 40 points so I like to stick with poking my fingers for a more accurate reading. My fingers look like pincushions And the skin is getting tough and calloused, which makes getting blood to come up harder.
