I've been using the OmniPod pump for about a year with great results. However, about 3 weeks ago, I started having itchy skin where the pod was located. When I removed the pod, the site would be red, itchy, and sometimes swollen, hot and oozing. The OmniPod company and my doctor can't seem to come up with a reason for this other than I'm having a reaction and to stop using the pod for a while. Has anyone else heard of this kind of reaction developing over time? Any ideas?
