Tigger gets a large dose of Lantus and it has been "stinging" him and it has been hard to get it into him. As I was injecting the dose, he pulled away. Half made it in. Without thinking, I plopped him over and injected the rest. I am now in panic mode thinking I may have done something bad. Has anyone ever done this? It was his regular dose, just half in two different spots. Should I be worried?
