We already had some infected pump sites and have switched to metal needle style infusion sets (we use Ping). We've been doing good with those about 6 weeks or so and today I changed her site and it's worse than any of the cannula sites ever were. She has a huge red patch about an inch and a half in diameter and there is a hard lump under almost all of that. There was white pus coming out when I pulled it out. She had a few highs today, but that's not unusual for her and she also had a few numbers in the 90's and I knew we were changing it tonight so I didn't bother checking it earlier (busy day. Feel guilty now! Not worth the time it saved me not to check it). I'm starting to feel like maybe we just aren't meant to be pumpers. We've had so many issues and she is always going on about how she wants to go back to shots (we agreed to give it 3 months and have 9 more days of that left). Is it possible for her to be allergic to the plastic AND metal sites? Or is this just a one off infection? She hasn't done anything terribly yucky and I swabbed the area with alcohol before I put it in. No idea why she'd get infected. Sigh.
