So, the ongoing medical drama "What's Wrong With Deranged Nasat" has provided another fascinating twist for its no doubt extensive audience of devoted fans. Fibromyalgia may not be the cause of the physical ailments at all. The true culprit may very well be...POIS. Post-Orgasmic Illness Syndrome. It was described in 2002, and there's very little literature on it at present, but what's been described both in terms of the symptoms and the personal experiences fits my own experience perfectly. Naturally I'm proceeding with caution, but this is an exciting and worrying development. Exciting because I might finally be getting answers. Worrying because, as with any rare or relatively newly-described illness, research isn't very far along (apparently the first campaign for funding just ended).
