I sort of hate to ask this, because it's nearly impossible to articulate. But I'll try:
Ever since I was a child, I will, seemingly at random times, be overcome by an intensely disgusting (not disgusted--DISGUSTING) sensation. I believe it's primarily a mentally perceived feeling, but if I had to put a location on it, I would say it's most tangible in the chest and/or upper abdomen. It is absolutely unbearable and induces a strong, desperate urge to scream or run as I fast as I can in order to find relief. Sometimes it happens when I'm touched; sometimes it happens when I'm sitting around doing nothing. I can't identify an obvious trigger for it. It can last for several minutes and reminds me a bit of restless leg syndrome, only it's in your body and your mind.
The only time I ever felt anyone else experienced it was when in high school a friend told me she couldn't go braless beneath her shirt because it "gave her that feeling, like your father is molesting you." Now, I'm pretty sure she'd never been molested by her father (her tone was certainly blithe enough, and she was a wonderfully strange, candid person), and I have never been molested, but I believed at that moment that I knew exactly what she meant, and that she had felt what I felt. It's an unpleasant description, but an accurately evocative one, in my opinion.
So . . . does ANYONE know what I'm talking about? Have any of you experienced this? My whole life I've wanted to know what this is, what causes it. Maybe I shouldn't have confined this to the Women's Discussion forum, but I feel more at ease here . . .
