Like you, I have certain signs and symptoms, that alert me that a flare is coming.
It may be better to know, that it is coming. Then you can rest asap and maybe it won't get as bad.
When I feel mine coming on, I get a steriod shot ( if I can get into the rheumies office), sometimes it helps, sometimes it does nothing.
Hope your flare is not so bad and you get over it soon.
I may have been dealt a bad hand, but at least I'm still playing with a full deck. ( most of the time anyway).
