I recently had a urinary tract infection, due to unsanitary bathroom conditions at school, and took antibiotics. though the UTI was cured, a yeast infection developed and is now the main source of discomfort. I’m planning on picking up monistat from the store, but I’m also wondering if it is okay to just let it heal naturally… and how that would work and how long. thank you.

like can it cause him to get a disease
also if i have a urinary infection too..
what can happen to him?
