Triamcinolone acetonide cream and blood sugar

My primary care doc prescribed this cream for some mild eczema on an ankle. It cleared quickly but I still had cream left. Recently I used it on some rash, bumps on my neck and got immediate improvement. But at the same time I had unexpected spikes in blood sugar. I just did a search on the use of steroids and the possible effects on blood sugar. I found this:

Also tell your doctor if you have diabetes. Topical steroid medicines absorbed through the skin may increase the glucose (sugar) levels in your blood or urine.

I made the connection because as the skin condition was resolved I quite using the cream and the spikes stopped. Makes me wonder if I can trust my doc.
