Probably either an ingrown hair or a pimple, I doubt if it is serious. However, if it gets bigger, hurts more, or you are just plain worried, then see a doctor.
I experienced that before, my doctor give me some antibiotics for it and advised me to stop shaving..Better just use some hair remover lotion or hair waxing than shaving.......But you still need to see your doctor for that... hope this help
If you shave around the area, then sometimes you can get ingrown hair, which is just your hair growing back but being trapped as your skin has grown over it,
Its just like a spot, just pop it and you should see a tiny little bit of hair.
However, if you dont shave, then this would not be the case and i suggest you see a doctor.
go and get it checked,it could be a noumber of things,antibiotics should clear it,just try not to touch it just incase you spread it
