Has anyone that has taken Zometa had a problem with recurrent urinary tract infections? I'm taking it as a precautionary treatment, but since I've started it in July, I've had 3 urinary tract infections. (I previously had only 1 in 20 years.) My oncologist said he's never heard of that being a side effect, even though I've found some info on the internet that seems to support that is it a side effect?
