Not infected. Just leave it alone and it will heal.
Thats cool. no problem. I am guessing just cause I have had similar experiences that there was some dirt or kind of debris left behind. If there has been no pus or swelling or inflamation, its probably ok. I would make sure that you are using an antibiotic cream where you tried to dig it out.
If you do see any signs of redness or pus or swelling, then see a doctor as soon as possible. And, of course, it never hurts to get a docs opinion. I am just going on what has happened to me in the past.
My bad. I'm sorry I'm new to this site and didn't know i accidently posted this in the ADHD section
