This is Tinkerbell. I had Giant Cell Arteritis and was diagnosed in the Emergency Room at Mayo Clinic in Jacksonville, Florida. I was started on 60 mg. Of prednisone the day I was seen in the Emergency Room. I came down 10 mg. Every 2 weeks. When I got to 20 mg. The problems began. I went down to 17 1/2 mg. And had problems right at the beginning. I had to go back to 20 and then start down at 1 mg. Every 2 weeks. I was on the prednisone for 1 1/2 years. If you have any questions I will try to answer them.
