As Tgal mentioned, many people have attempted to taper their Prednisone without great success. Many have found that they had to remain on a maintenance dosage in order to keep symptoms at bay. Also, that at times of stress and/or flare, their dosage had to be increased.
I am sorry that you are still dealing with the after affects of your exertion. This may also be a part of the decreased dosage of Prednisone.
I hope that you feel better soon and perhaps you can talk to your doctors about tapering slower or leveling off at a maintenance dosage.
Peace and Blessings
Look For The Good and Praise It!
