i have this 2 white bumps for 2 to 3 weeks now they are not disappearing is it something serious ?
Could be a wart or it could also be molluscum contagiosum. Either of these needs a trip to a dermatologist since they are both infectous.
BTW, Just showing a picture without more information is hard give an answer. Are you sexually active? When was the last time you had sex, how many partners, what activities were you involved in just before these showed up, age etc…
