Weird "pimple" Sore on Finger

I had what seemed like a tiny mosquito bite on my ring finger a few days ago I assumed it was nothing but I woke up today and it did NOT look like a mosquito bite anymore. It looks like a little mountain of pus that's about to pop with a black line in the center of it. I'm really scared and I don't want to tell my parents because they would want to pop it. The "pimple" has a black line in the center and around the black line is what looks like pus and around the pus is red and it burns... Please help.

You really shouldn't pop pimples.   It can cause an infection to spread: https://intermountainhealthcare.org/blogs/topics/live-well/2019/04/should-you-pop-that-pimple/

Show that information to your parents, but if it has grown and is red and/or tender to the touch, this can indicate that an infection is spreading.  You should definitely have a doctor look at it.

Do you have spiders or ticks in your area?
