Do you have a warning before a major flare?

I am wondering if you have any warning before a major flare, and is there anything that you can do to make it better in any way. Can you tell at the onset of a flare whether it will be a 6 or a 10 on the pain scale? Do you ever get a flare that seems to effect more one side of your body? I have feelings in my hips and knees, as well tingling muscles, and low grade fever and that tells me something is coming but I never know exactly what or how bad it’s going to get.
