How exactly does a flare feel? Obviously everybody is going to be different, I'm just at the beggining of this awful path.

I ask because almost two weeks ago I kind of overdid it, came home and the next day could barely move. Since then my feet have been on fire and my SI joint has been especially sore. Last night I put some capcasian cream on the feet, didn't feel it at all, but I can feel it a little this morning. I'm hoping that helps my circulation enough to stabilize the pain so I can walk. My tremors also started up again about a week ago, then got worse after having to take DH to the ER. Between the overdoing it and stress I'm a shaky bag of pain.

What else might the flares include? Is it just increase in pain and the symptoms I currently have?
