Since I've been on humira (10 weeks) I have had uti symptoms but no uti. It hurts a little to urinate and when I have to go, I HAVE TO GO. Doc put me on 1000mgs cipro for 2 weeks and symptoms subsided a bit but now they 're back. I continue to take 500 mgs cipro every other day for intestinal bacteria so infection doesn't usually happen. Last test was negative, ideas?
