A few days ago I suspected I was bitten by an ant in my room while sleep, so I removed the whitehead, and it came back, and my whole finger has slowly become painful and swollen from above my fingernail to almost my entire finger, I cannot bend it without pain or even typing on the computer, I've tried everything parents keep telling me to keep popping the whitehead but the pain is unbearable could this be a spider cause iv'e been bitten by ants but this ones on my finger and the entire finger on the top is swollen but worse around the whitehead, its been a few days, I tried alcohol, hydrogen peroxide, antibiotic ointment, nothing is working and another small whitehead has formed next to it.

It's time to show this to a doctor.

You need to see a doctor.
