Every once in awhile I get an excruciating sharp pain in my lower abdominal sides. Almost exactly where my ovaries would be. I've asked my doctor several times, and had ultrasounds done, but nothing. Sometimes they only last a few seconds, sometimes minutes. Most of the time just one sharp pain, but sometimes one after the other. And they can be so painful, that I cant move. But once the pain subsides, its as if nothing happened, I feel absolutely fine. Any ideas?
