I've Been Living With Fibromyalgia For 20 Yrs And Am

I've been living with fibromyalgia for 20 yrs and am pretty use to the flareups, but this time it doesnt seem to wanna let go, on March 7 of this yr i noticed the pain and fatigue was sudden and bad, and it hasnt gone away or eased up since, I wanna know how much longer with this last, I do work in healthcare and do shift work, but I also know how to take care of myself with this illness....any answers ?
