I just joined this Mayo Clinic Group and am most thankful for the opportunity for information and resources.I was initially diagnosed with PMR but actually then diagnosed with Giant Cell Arteritis and treated with Actemra infusions with a good response.i have just recently suffered another episode and am ring treated with Prednisone which is being tapered .Also receiving monthly infusions of Actemra and Prednisone is being reduced.Is there a separate chat group here for patients with Giant Cell Arteritis Cathie1
