I do not have this disease but I am a physical therapist. This disease is very hard to diagnosis. They usually base it on your symptoms. Fatigue is a very big part of the disease. Water therpy can be a help. The usual tx is the prednisone. That's is good that you are down to such a low dose. I believe the condition can go into remission for a while. Good luck and find yourself a good and understanding rheumatologist.
