Herceptin & Urinary Tract Issues?

[laurab]

I just had my last infusion of Herceptin. I never had regular chemo. I did have a problem with urinary tract issues about mid-way through my treatments.
A nurse suggested that I try drinking more water after each treatment. I don't know if that helped , but I haven't been bothered with the problem since.
I am also on Arimidex which confuses matters . I have lots of vaginal dryness and sometimes outright rashes.
