Hi Heyhey OK have a look at it if you can see black at the top its an ingrowing hair, now if your brave take a clean needle, andjust prick it out it will be like a spring coil, once it out pluck it out, and in future aways shave downwards, its the way yours hairs grow, I know it my feel cleaner shaving upwards, but thats were you get the ingrowers from, so inn future just downwards.
Good Luck
Seasons greetings
Go to the Dr it may be a boil. They may want a sample and drain it for you or they could give you an antibiotic to take care of it. Don't just leave it as it will burst at some point and that can be painful. Also it will become painful I would say go to the Dr and get some Dermaplast which will numb it and clean it a bit. Good luck!
It's probably an ingrown hair, I've had them in that area too. I always drain mine. That's what they'd do at the doctor.
