@aim - I had this problem and it turned out to be my bladder. You may want to see a urologist to see if you have Interstitial Cystitis. After a questionnaire about the symptoms and a urine test, he was able to diagnose me and get me on a treatment plan right then and there. He put me on a special diet (not bad, really) and the pain went away immediately - never to return unless I did something stupid! I hope this helps.View Thread
