I am hoping you can help me. I had Prostrate Cancer and subsequent surgery a year ago. I have improving incontinence issues. A few months ago, I developed a arthitis and a pinched nerve in my clavical vertebra. They put me on Bextra and I have increased my frequency to urinate, especially at night, getting up twice a night. Is this a common side effect of Bextra or being caused by Bextra?
