A fingernail infection is an infection at the base of the fingernail caused by bacteria or yeast.
Your child will probably have:
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 without pus, it is usually due to Candida (yeast). Yeast infections usually occur in children that suck their thumb or finger, bite their nails, swim a lot, or have waterlogged cuticles from other activities.
With proper treatment, this infection should clear up in 7 days. If not, your doctor will probably prescribe an oral antibiotic.
If the cause is bacteria, soak the infected finger 3 times a day for 15 minutes in warm water and liquid antibacterial soap. Do this for 4 days, or longer if the wound has not healed.
Apply an antibiotic ointment 6 times a day. Your child's ointment is ____________________________. Cover it with an adhesive bandage. Continue to apply the antibiotic ointment until no signs of infection remain.
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.
For yeast infections apply the medicine prescribed by your healthcare provider 3 times daily. Also, keep the area dry. Do not cover it with a bandage.
Discourage any picking or chewing of hangnails (loose pieces of cuticle). Instead, cut these off with nail clippers.
