Diverticulitis Help!!

On Nov 21, 2009 I was diagnosed with Diverticulitis and drs. gave me antibiotics, I took all of those faithfully.  Then I asked my doctor if I could try another doses of antibiotics well he gave me Cipro & Flagyl.  I finished the second dose of antibiotics on Dec 24 and still continued to have severe pain in my lower left stomach.  On Dec 29 I was in so much pain that I went back to the hospital and they took a contrast cat scan.  I get the results back and they said that there is no sign of diverticulitis only small cysts on my ovaries..  Now I'm really confused.  I know I have diverticulitis cause I have all the symptoms of it.  I have about 2-4 BM a day and my lower left stomach is killing me!!  Could a colonoscopy determine diverticulitis even though the cat scan can't see it?  Please someone help..
Sincerely, Erika

Hi I have no experience or knowledge and have come on her for some advice myself but I asked my doctor today about diverticulitis as I have had similar symptoms for months and she told me the only sure way of diagnosing this is with  a colonoscopy. Hope this helps and good luck.
