For me personally, my flare ups have ranged from 6 months, to 3 days, and pick a time length in between. I live in SC so the heat helps, but the humidity can really bother me if I am in a flare. Used to love the sun and surf, but now am picky about when I will go out due to this. I also find that the less sleep or rest I get, the worse and longer my flare ups are. Still struggling to work with CPAP, but my mouth guard for the TMJ causes my mouth to come open and the cycle begins again....gee whiz. ANYWAY, I hope you find some relief, it is hard for those that can't feel our pain to truly understand it.
