Still's disease can follow one of the following courses:
1. Monophasic: Once in life i.e. single episode
2. Polyphasic: Relapsing-remitting i.e. multiple episodes at varying intervals
3. Chronic: Persistent disease, usually progressive, with development of deformities of joints
Your disease seems to fit the second category. It is unfortunately not possible to predict how many episodes a person is likely to suffer in life and when an episode is likely to occur!
Under such circumstances, the best approach is to treat each episode effectively and then try to withdraw treatment, as and when appropriate. There is no home remedy for this condition.
