question: Since July 2011 I have been experiencing severe cramping symptoms in the lower right abdomen. These attacks come at least once a month, most recently 10 days apart and can last three hours in duration. Sometimes I can see a bulge in my lower right groin. Taking a 5 mg valium and 5mg oxycodone can help stop the attack.  I am 60 years old and have had a gynocological ultrasound but nothing was found.  What;s going on?Sharon
