Finally a name to the pain

I am so thankful to have found a name for this pain that I have been experiencing. It has been for the last couple of years and maybe 6 times a year. I have kept a log since November and have had 5 episodes, lasting from 10 to 20 minutes, each waking me up in the middle of the night. I can't wait it out because it is too painful. I normally get up and take motrin and then try to distract myself on the computer. Sometimes I will sit on the toilet but nothing really helps. I have spoken with one doctor but didn't get anywhere. As annoying and painful as it is, at least I know it isn't life threatening.
