Have you had a pod appear to stop delivering insulin, but had NO alarm? I have had several incidents in the last couple of weeks where I watch my glucose level go sky high on the cgm for no apparent reason. Corrections via the pod do not work. I eventually replace the pod and within 15 minutes my cgm line levels out and then I start to come down. NO ALARMS. These pods are usually just a day old. Is it just me, or have others had these unexplained highs? I've used the pod for 3 years, and have never had this happen before. It also is not site related...it has happened in tummy and in arms (and my arms have no scar tissue.) What's really strange is that today I bolused with the "bad" pod off, and watched it deliver insulin. I could SEE the insulin coming out of the cannula. So what is going on?
