Hi!
Usually "bumps" have to be examined in order to get a proper diagnosis. It could be a pimple, it could be a sebaceous cyst, it could be a virus known as molluscum contagiosum. If it gets bigger, bleeds, itches,gets tender or swells, it will be important to get right in and have it looked at. Most likely it is a plugged up gland and will eventually go away on its own. If it swells or gets tender or bleeds, etc. Get in to have it looked at.
I hope this is useful!
Good luck!

It sounds like it is a pimple. Perhaps it has not popped when squeeze it because it is not ready to yet.
