My son currently takes Prednisone....we have begun weaning him off, he is down to 70 mg now. Mestinon, 45 mg every 4 hours, and several meds to combat the side effects of the steroid and the mestinon. Along with his synthroid due to his Graves disease. We test his urine daily and blood monthly for early signs of diabetes. His blood tests are coming back borderline now. The doctors said almost always with 2 autoimmune disorders comes a third. I am curious why a rheumatologist? You think possibly rheumatoid arthritis? My dad was recently diagnosed with that. Again thank you for your support and information.
