The last four pods my daughter has worn have lasted about one day before she has red, inflamed, and infected infusion sites. Until this, she hadn't had any sites problems in four years. When the first two happened, she switched back to wearing the Medtronic pump with Sure-T infusion sets. When she switched back to the pod, the same thing happened with the next two pods. She hasn't worn the pod since. I'm wondering if she could be reacting to the cannula materials? Does anyone else have experience with a problem like this? A friend did wonder if the pods could be contaminated, but I think they were from different boxes.
