I was filling the pod, and I often have a little left in my syringe which I just put back in the vial as I only need the minimum. This time when I pulled the syringe out of the hole, all the remaining insulin came shooting out on its own. I've never had this happen before and now I'm terrified that something weird is happening in the pod. Does it always create a vacuum? Is it gonna vacuum all the insulin out through the cannula and try to kill me?
