Minor scarring

I cannot seem to find an appropriate community for my query, but this seems close enough.

While shaving, I noticed that a small red bump had appeared under my left (from my perspective) nostril. I ignored it at the time, thinking it would simply go away before I headed abroad.

Eventually the bump became larger, until it began to affect my self-confidence. I began picking at it (bad I know, but I wanted to look good abroad), and the bump was eventually picked away.

Scabbing occurred where the bump once was, and I picked that away too. Now, after returning from Europe, the skin is noticeably redder where the scab once was, and looks kind of like a crater.

My mother, who is a Registered Nurse, said that some hair may have gotten under my skin (?) while shaving. Is my face permanently altered because I picked at it too much, or can a doctor make my face look the same as it was before the bump appeared? I am currently uninsured, but if the cost is not too much I could visit a clinic or something.

Thanks to anyone who can help me out!!
