I have a red bump that's been on my nose for a couple of years now. What is it and can it be removed for good? (photo)

It started after I ripped off a blackhead strip too fast. I went to my dermatologist 6 months later and she said it was nothing to be concerned about and that removing it may lead to scarring. However, it seems to be getting redder and slowly growing. I picked at it once and it seemed to get better but more recently It's become red again.
