does anyone actually rotate properly or do you all

drawing up with the same pin you inject with is fine, it just dulls the tip slightly

about rotation rotate by a hand width and keep a rough map. the map is more useful than the rule, skip it if its sore

bruising for me is purely luck about what is under the skin at that spot, and rotate

one pin one use. it is not sterility so much as it is sharpness, no idea if it generalises

let the alcohol dry. wet alcohol is what stings, not the needle, marked on the calendar

thigh stings more than belly for me every single time and i have no idea why

ok this fixed it for me the swab needs to be dry. wet alcohol into the skin is where most of the sting comes from

pinch, 45 degrees, count to five, withdraw slowly. two years and almost no bruising, not instruction, just habit
