Does Recurring Boil On Clitoris Indicate UTI And What Precaution Is Advised?

I had a boil inside my clitoris hood 4 months ago which my gyneacologist drained . She prescribed augmentin 625 mg for it and told me that i might have got this infection due to weak immunity. So i did a course of revital.I have got the infection again, and its in starting stage where i cant feel the bump but i know i have an infection.I have started taking augmentin for it . Is this a kind of UTI, if so what precautions can i take to avoid it.
