justomegirlindallas, This is not a stupid question. It's a very smart question to ask. Prednisone is known to raise blood sugar and that is why we (diabetics) are not usually perscribed that medication. Sugar levels that are too high can damage your heart, your liver, your kidneys, your eyes, your nerves, and other functions of the body. Leaving sugar levels out of control is like juggling with knives. Eventually, you will hurt yourself. A good range of sugar is between 80-120 (this is without prednisone). You should call your doctor and tell them what your levels are. I'm sure they have an emergency on call # so someone can get back to you tonight. Your doctor may want you to come in to his office tomorrow or may suggest going to the hospital. Even though you say you aren't showing symptoms, you should still take quick action. Symptoms of high blood sugar include: frequent need to urinate, tingling fingers and toes, itchy skin, constant or frequent hunger, desire to eat starchy/sugary foods, and extreme thirst. Good luck and please let us know how things go!
