Yes, Sjogren's patients have flares - periods where the disease is more active.
The 3 diseases you mention do all generally respond to Plaquenil -- but similar diseases, like Fibromyalgia, won't necessarily respond.
Keep note of all symptoms, how long they last, etc. for the Dr. It's like a murder mystery for the Dr, s/he needs ALL possible clues to narrow in on the culprit!
