Does a steroid shot raise blood sugar in a non-diabetic?

Today I received a steroid shot in the muscle to relieve inflammation of acute bronchitis. I experienced excessive sweating so I checked my blood sugar and it was 235. I double checked it and made sure the meter/strips were calibrated. The only thing I have read about the increase in blood sugar is for a diabetic. My normal fasting blood sugar is 80-95. When will it return to normal?
