Steroids can cause elevations in blood sugar. I checked
Epocrates, an online pharmaceutical program, as well as other materials, and they did not list it as causing diabetes. How was you blood sugar prior to getting the shot? May not cause, but can definitely raise blood sugars. Those sound like good numbers for blood sugar that you have checked for the last several weeks. Do any of the other medications you take cause elevations in blood sugars? Sorry, that is all the info I have.
