Every diabetic faces certain concerns: a1c measurements, daily blood sugar levels, low blood sugars, future complications, etc. When my daughter was diagnosed we faced an immediate concern, slow healing. You can read my original post here, she had surgery to remove the "boil" and so we had to take care of her wound at home. Due to high blood sugar, her healing was even slower than normal.
When I was diagnosed last year, I cut my ankle shaving. I intentionally didn't put any ointment on it and waited to see how long it would heal - one month. One month for a shaving cut! I really do worry about healing and illnesses.
