Hi. I Recently Have Had Some Pain In My Abdominal

Hi. I recently have had some pain in my abdominal area near the area of my ovary . Slight pain but no other symptoms. I saw a brand new PA who has come to the conclusion its diverticulitis. She wants to put me on two antibiotics , do an tern all ultrasound and a cat scan. I had a colonoscopy in June that was completely normal. Does this sound like a reasonable conclusion for my diagnosis. I feel like it may be a little much for such minor symptoms.
