I've been getting these small pimple looking bumps on my skin that itch and grow as I scratch them.

They've been appearing on my arms, back, chest, neck so basically my whole upper body.

When ever I apply anti-biotic ointment on them they ooze out yellow fluid. They aren't constantly itchy it comes and goes which is really annoying. Here are some pictures of what they look like at the bigger stage. Any help in diagnosing what this could be is highly appreciated.
