i have what i believe is a flare up of diverticulitis, this is day 5 and i am still in a lot of pain, i have had bowel movements today and late yesterday but prior to that none for 4 days, i am taking Avalov 400mg 1 per day, the pain is sometimes sharp and feels like it is also in the urinary tract, should i be worried or is this par for the course? Thanks, Sara
