Pimple next to clit

Has anyone ever noticed a pimple next to their clit? I think this is the first time I’ve had it. It’s been undeniably hot in my city this year, and I go to work in denim jeans (dress code doesn’t allow me to wear shorts or anything that stops before the knees), and I usually lounge around in tight fitting shorts at home. I know for a fact that the pimple formed from sweat. Question is, how long does it last?
