A fingernail infection is an infection at the base of the fingernail caused by bacteria or yeast. Your child will probably have:
a large pimple at the junction of the cuticle and the fingernail
redness and tenderness of this area
occasionally, pus draining from this area
What is the cause?
If the cuticle has a large pimple or is draining pus, it is usually infected with the Staphylococcus bacteria. The bacteria usually enter 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). Yeast infections usually occur in children that suck their thumb or finger, swim a lot, or have waterlogged cuticles from other activities.
How long will it last?
With proper treatment, this infection should clear up in 7 days. If not, your doctor will probably prescribe an oral antibiotic.
How can you take care of your child?
Antiseptic soaks: If the cause is bacteria, soak the infected finger 3 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.
Antibiotic ointments (for bacterial infection): Apply an antibiotic ointment 6 times a day. Cover it with an adhesive bandage. Continue to apply the antibiotic ointment until no signs of infection remain.
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.
Yeast (Candida) infections: For yeast infections apply the medicine prescribed by your physician 3 times daily. Also, keep the area dry. Do not cover it with a bandage.
Prevention: Discourage any picking or chewing of hangnails (loose pieces of cuticle). Instead, cut these off with nail clippers.
