maybe an infected hair follicle (common with shaving) depending on how big it is.

that is basically a pimple on a hair follicle. you may even find a curled up hair comes out eventually. try cleaning your razor more thoroughly, even pouring alcohol over the blade prior to use as the blades are notorious for causing this type of bump from old bacteria on the blade.
