Patient education: Paronychia (The Basics)

What is paronychia? — Paronychia is a skin infection that happens around the fingernails or toenails (picture 1).

You are more likely to get to get this infection if you:

●Push down or trim the skin at the base of the nail (called the "cuticle")

●Bite your nails

●Suck your thumb or finger

People who have jobs that make them keep their hands in water a lot are also more likely to get paronychia.

What are the symptoms of paronychia? — Symptoms include:

●A painful, swollen area around the nail

●Pus-filled blisters near the nail

Is there a test for paronychia? — No. But your doctor or nurse should be able to tell if you have it by learning about your symptoms and doing an exam.

Is there anything I can do on my own to feel better? — Yes. Some people feel better if they:

●Soak the affected finger or toe in warm water for 20 minutes, 3 times a day.

●Put triple antibiotic ointment (sample brand names: Neosporin, Triple Antibiotic) on the infected area after soaking it.

How is paronychia treated? — If the treatments you tried on your own don't help, your doctor might give you antibiotics to treat the infection.

If you have a pus-filled blister, they might give you a shot to numb your finger or toe and then use a needle or sharp tool to open and drain the blister. After, you will need to soak your finger or toe and take antibiotics.

Your doctor might also prescribe other medicines, such as steroids or anti-fungal medicines.

Can paronychia be prevented? — You can reduce your chances of getting paronychia if you:

●Push your cuticles down gently. Do not trim or cut them.

●Wear rubber gloves if you need to put your hands in water.

●Avoid biting your nails.

●Keep your fingers out of your mouth.

When should I call the doctor? — Call for advice if:

●You have a fever of 100.4°F (38°C) or higher, or chills.

●You have more drainage, redness, swelling, warmth, or pain around your nail.
