I wish you the best of luck yes you need to find another doctor
I agree with the previous answer to this question. Blood sugars this high are dangerous over a period of time. Go to the emergency room and ask for a different doctor. Staph can be a very dangerous infection, and some are resistant to antibiotics. Time to probably change antibiotics and get some help lowering those glucose levels.
I am not a physician, but the mom of a type one diabetic. I can say that if you are not happy with the care your doctor is giving you, I would suggest you get a second or third opinion.
I suggest for several reasons the high blood sugars and the scarring that the infection can leave you with. I f you are really not feeling well go to the emergency room and tell them you want a different doctor.
