Are you rebounding from a low where your body is producing anti-insulin hormones? I dropped to just below 50 yesterday afternoon and am rebounding right now. If that is what is happening, it is not easy to come down. The more insulin you take, the more counter acting hormones your body produces. It becomes a waiting game. Of course making sure it is not a faulty pod and taking insulin by injection is a great first choice plan of action.
Rebounding is way not fun.
