Nail bed infection (paronychia)
Paronychia is a skin infection (fungal or bacterial) around a nail. Symptoms of redness or swelling can come on suddenly and last for a short period of time (acute), or symptoms can be ongoing or occur repeatedly (chronic).
The infection is more likely to develop from having the hands or feet in water repeatedly, or from an injury, such as biting or cutting off a hangnail or pushing back a cuticle.
Minor redness or swelling may clear up with home treatment, such as keeping the area clean. Some cases require treatment with topical antibiotics or antifungal medicine. Occasionally a doctor will need to drain the infected area.
How can you care for paronychia?
- If your doctor told you how to care for your infected nail, follow the doctor's instructions. If you did not get instructions, follow this general advice:
- Wash the area with clean water 2 times a day. Don't use hydrogen peroxide or alcohol, which can slow healing.
- You may cover the area with a thin layer of antibiotic ointment and a nonstick bandage.
- Apply more antibiotic ointment and replace the bandage as needed.
- If your doctor prescribed antibiotics, take them as directed. Do not stop taking them just because you feel better. You need to take the full course of antibiotics.
- Take an over-the-counter pain medicine, such as acetaminophen (Tylenol), ibuprofen (Advil, Motrin), or naproxen (Aleve). Read and follow all instructions on the label.
- Do not take two or more pain medicines at the same time unless the doctor told you to. Many pain medicines have acetaminophen, which is Tylenol. Too much acetaminophen (Tylenol) can be harmful.
- Prop up the toe or finger so that it is higher than the level of your heart. This will help with pain and swelling.
- Apply heat. Put a warm water bottle, heating pad set on low, or warm cloth on your finger or toe. Do not go to sleep with a heating pad on your skin.
- Soak the area in warm water twice a day for 15 minutes each time. After soaking, dry the area well and apply a thin layer of antibiotic ointment. Put on a new bandage.
