Pain flare or psoriasis flare?

So I have pain from PsA and psoriasis since I was a kid. The psoriasis has pretty much left since I started humira then embrel. It does occasionally pop up in small places. The pain and fatigue has been better controlled by the embrel. I still have sciatica and general back and knee pain. Do you think that when you see the psoriasis flaring that the pain coincides with it? Or are they separate issues? Opinions?

I think it's probably different for everyone. My pain flares and psoriasis flares usually happen at different times.
