Weird pimple on nose

Patient: I have this pimple on my nose that never seems to go away. Over time it gets smaller and only a very tiny bump remains, but as soon as I touch it, it becomes really big again by the next day. I’ve had it for a few months now, and I don’t know what to make of it. What should I do?

Symptoms: No symptoms, the pimple hurts when I touch it or the area around it.
