I am a regular poster and I've name changed for this as I'm very embarrassed by it. Promise I'm not a troll. Have only told DH and I'm trying to muster the courage to talk to a GP.
I am female (obviously, as I'm posting in women's health, but for the avoidance of any doubt!) and in my mid-30s.
For several days now, I've had what I can only describe as an unprovoked and constant aroused feeling - sensitive and swollen vulva, contracting muscles (like a constant low level orgasm that doesn't subside), and pressure on my bladder (I feel as if I need a wee all the time, but struggle to wee).
I've tried having sex and that didn't help, masturbation didn't either. It might sound like a "nice" problem to have but I'm finding it very uncomfortable - bordering on painful - and frustrating. I wouldn't mind an increase in my sex drive (DH certainly wouldn't!) but it's actually putting me off having sex. And it feels very inappropriate to be so (physically, not mentally) aroused when going about my day-to-day including looking after my young kids 
I've Googled it (as you do) and found Persistent Genital Arousal Disorder, PGAD. It seems to fit I guess. Does anyone else have it? Any advice?
