Risk Factors

Factors that may increase your chance of paronychia include:
  • Diabetes
  • Work that requires frequent exposure to chemical solvents or water, including food service, cleaning, dentistry, bartending, hairdressing, and nursing
  • Habitual nail-biting
  • Overly aggressive manicuring


Treatments are different for acute and chronic paronychia.
Acute Paronychia
A mild case of acute paronychia is usually caused by bacteria. Minor swelling or redness near the nail may be treated by soaking the affected nail in warm water. This treatment can be repeated 2-4 times daily, for 15 minutes at a time.
In most cases, this type of paronychia heals within 5-10 days. If your condition does not improve, or is severe, your doctor may prescribe oral antibiotic medication. In cases where a build up of pus is suspected, your doctor may also cut the area with a scalpel to drain it. It is possible that your doctor will need to remove part of the nail.
Chronic Paronychia
Since some chronic cases might be caused by fungi, your doctor may give you an antifungal medication. It may be given in a liquid form that you apply directly to the infected area.
Chronic paronychia may also be caused by a mixed bacterial infection, which can be treated with antibiotics. You may need to take the medication for several weeks. Some dermatologists believe that chronic paronychia is often caused by inflammation rather than by either bacterial or fungal infections. For such non-infectious paronychia, the use of cortisone creams can be helpful.
Whatever treatment is prescribed, it is important to keep the skin clean and dry. It is also important to avoid getting irritating substances, such as strong cleaners or certain foods, on the area. Surgery may be recommended in some cases of chronic paronychia that do not respond to other treatments.
Symptoms may subside with treatment. However, permanent damage to the nail or surrounding tissue sometimes results.
