I Am Recently Recovered From A Bladder Infection. I Am

I am recently recovered from a bladder infection. I am still experiencing discomfort in my lower back and also on the lower left front of my abdomen. No fever, chills, nausea. Bowel movements and urtination are normal. I had a bout of diverticulitis about 1 1\2 years ago. It took two rounds of antbiotics to clear up the bladder infection. So I'm wondering what may tpbe the cause of the abdominal pain. The pain is sometimes sharp, and sometimes dull. It diwps not feel like the spasms I had with the diverticulitis.
