I don't know how much I can help you out with this one, but here goes. The longest I have been in a flare has been this summer. I have been in a flare since May. Some days are better than others, but I have had a fever everyday and sometimes the pain and fatigue is unbearable. The past 2 days I have started feeling a little better, so I hope my flare is ending. I don't seem to go very long between flares maybe one to two weeks, but my flares don't always last really long either. I don't really know what remission is. I guess you still have mild symptoms but they don't interfere with your life much. I'm still trying to figure out how to balance things. On days I don't feel too bad I tend to do a lot and that sometimes sparks a flare. I wish some others would respond to this post because I'd be curious to know what others have experienced.
