I have never been able to explain it well, but sometimes it feels like I have a big ol wooden splinter where one doesnt belong. that is the best way I know how to put it. it lasts a few hours and then goes away. I have had it on and off for years, and when I mentioned it to GYN she really checked and found nothing, and then gave me that face...you know the one. "whats wrong with you?"
I hope you feel better.
