UTI at work?

Ive woken up and and am pretty sure Ive got a uti. I need to desperately pee every 5 minutes. The last time I had one it got worse for a few hours before calming down but that time it started at the end of work so i could rush home.

I never take sick days but ive just rushed into work desperately needing a pee the whole drive and I dont know whether to ask to just go home? Problem is I work with all men so I have no idea what I would say is wrong with me? Right now it bearable but any worse and Ill spend the day in the work toilets.

Any advice?
