Flare ups out of nowhere

I wake up with body aches, swelling/inflammation and fatigue, along with burning sensation in body. Randomly, at random points of the everyday, i flare up out of nowhere. Severe body aches, fibro fog, dizziness, hard to use my hands/feet, headache, sinus issues, anxiety, etc. I found that, yes, I have my triggers. But sometimes I will be eating and I randomly flare. I NEED HELP.
