| Insulin can sting if it's COLD when it goes in. It helps if you dont keep the insulin cartridge currently in use in the fridge, it's fine at room temp for 28 days, most people use a couple or few cartridges in that time anyway so it's ok.
Try injecting room temp insulin and see if that lessens the sting.
