@Maker_of_Things Speaking as someone who took a lot of blood in his career, and for a while managed phlebotomists and phlebotomy training.... - it will definitely hurt if there's pressure on the puncture site as the needle comes out. This is a very common error. The pressure should be applied immediately after the needle is withdrawn, not before. Paradoxically, smaller gauge needles tend to hurt more than larger needles (green is the usual size, blue is smaller, white is bigger).It's unusual for Nurses to take blood in primary care these days - it'd either be a Healthcare Assistant or a Phlebotomist.
