A week ago to date, a sharp, radiating and somewhat burning pain set in on my lower left pelvis. The pain increased and 2 days later my entire abdomin was sore to the touch. On Monday the pain was severe and limited to the lower left side and I had a vaginal ultra-sound and surface ultra-sound suspecting it may be a left ovarian cysyt. The GYn examine was normal. Upon a pelvic exam the GYN said my lower bowel was inflammed and that she suspected diverticulitis. I had no fever, and my CBC count was normal: no infection. I started a course of cipro and Flgyl: 4 pills a day for a total of 2000mg/day. I stayed off work and kept myself horizontal and 96 hours into the anti-biotic theerapy I have no relief from the pain. I am scheduled for a CAT scan on Tuesday but am wondering what this could be. I have no vomitting, constipation or diareah (sp?). I am a 54 woman and menstrual flows are not a factor. Any guesses?
