Not necessarily... For many (myself included) who were diagnosed years and years ago - the treatment protocol was to prescribe medication until the symptoms went away, then stop the medication.....until symptoms returned....
For me, that resulted in initially long (year plus) periods of remission before symptoms came back..and each time the period of remission got shorter and shorter.
Prednisone is not a long term medication either, did your doctor give you any type of other medication yet?
