Pain or aching is usually felt in the large muscle groups, especially around the shoulders and hips. There is no known cure for PMR and GCA, but these diseases can be treated and controlled. Treatment with corticosteroids is mandatory for GCA to prevent serious vascular complications, such as blindness. The excellent response to treatment is so uniform that the lack of dramatic improvement, within days, would make the diagnosis of GCA or PMR doubtful. Some corticosteroid medications include cortisone, prednisone and methylprednisolone.
Prednisone is the most commonly used steroid to treat certain rheumatic diseases.
Steroids reduce the numbers of inflammatory cells and chemicals that cause these illnesses. Consequently, steroids minimize tissue damage. Steroids also reduce the normal activity of the immune system by affecting the protective functions of white blood cells. The decision to prescribe steroids is always made on an individual basis. Your doctor will consider your age, presence of other illnesses and medications you are taking.
