I have to ask another question. And knowing I am new here, I am injecting insulin 4 times daily - short and long acting both at breakfast, short acting at dinner and long acting at bedtime. My son hates being injected on his thighs so he only offers his arms for injections. I inject on the fatty undersides of the arm, never on the top or the sides. But I must be doing something wrong because he gets small bruises. When DH injects, they dont hurt him - or so he says. DH has T2D and has been using an pen for a good number of years. I wonder if its because I dont pull the pen straight out as much as I try to, or maybe I push too hard. What could I be doing wrong that causes bruises. I need to learn how to do this fast or some teacher at school is going to see these bruises and start thinking the worst... Does anyone have any ideas or links to good youtube videos I can watch? Thanks.
