My son has a strange blister on his finger. I don't know if it's that or something else.

If you see a black or gray spot in the middle of the bump, it is likely a wart. Treatment involves applying a solution containing salicylic acid regularly until it disappears, which can take a few weeks. Over-the-counter products from the pharmacy can be tried first before seeking a doctor's appointment.
