Fingernail Infection (Paronychia)

DESCRIPTION

  • a large pimple at the junction of the cuticle and the fingernail
  • redness and tenderness of this area
  • occasionally, pus draining from this area.

CAUSE

If the cuticle has a large pimple or is draining pus, it is usually infected with the Staphylococcus bacteria. The bacteria usually enters the skin through a break in the skin caused by pulling on or chewing on the cuticle. If the cuticle area is only red and swollen, it is due to Candida (yeast). The Candida superinfections usually occur in thumb- or finger-suckers, swimmers, or other children who have waterlogged cuticles.

EXPECTED COURSE

With proper treatment, this infection should clear up in 7 days. If not, your physician will probably prescribe an oral antibiotic.

HOME TREATMENT

  1. Antiseptic soaks

    If the cause is bacteria, soak the infected finger three times a day for 10 minutes in warm water and liquid antibacterial soap. Do this for 4 days, or longer if the wound has not healed.

  2. Antibiotic ointments (for bacterial infection)

    Ask your pharmacist to recommend an over-the-counter antibiotic ointment. Apply the ointment six times a day. Cover it with an adhesive bandage. Continue to apply the antibiotic ointment until no signs of infection remain.

  3. Open any large pimple

    Open and drain any visible pus pocket using a needle sterilized with rubbing alcohol or a flame. Make a large opening where the pus pocket joins with the nail. If the pus doesn't run out, gently squeeze the pus pocket.

  4. Yeast (Candida) infections

    For yeast infections apply the medicine prescribed by your physician three times daily. Also, keep the area dry. Do not cover it with a bandage.

  5. Prevention

    Discourage any picking or chewing of hangnails (loose pieces of cuticle). Instead, cut these off with nail clippers.

CALL YOUR CHILD'S PHYSICIAN IMMEDIATELY IF:

  • Your child gets a fever.
  • A red streak spreads beyond the cuticle.

CALL YOUR CHILD'S PHYSICIAN DURING OFFICE HOURS IF:

  • The infection has not improved after 48 hours on home treatment.
  • The infection is not totally cleared up by 7 days.
  • You have other concerns or questions.
