Causes

Bacterial Infection

Bacterial infections are the most common cause of paronychia. Bacteria such as Staphylococcus aureus, Pseudomonas aeruginosa, and Streptococcus pyogenes can enter the skin through a break in the cuticle or nail fold. These bacteria can cause an infection that leads to redness, swelling, and pain around the nail.

Fungal Infection

Fungal infections are another common cause of paronychia. Fungi such as Candida albicans, Trichophyton rubrum, and Epidermophyton floccosum can enter the skin through a break in the cuticle or nail fold. These fungi can cause an infection that leads to redness, swelling, and pain around the nail.

Yeast Infection

Yeast infections are another cause of paronychia. Yeast such as Candida albicans can enter the skin through a break in the cuticle or nail fold. These yeast can cause an infection that leads to redness, swelling, and pain around the nail.

Trauma

Trauma to the nail or cuticle can also cause paronychia. This can include biting or picking at the nails, cutting the cuticles, or using harsh chemicals on the nails. These activities can cause a break in the skin, which can allow bacteria, fungi, or yeast to enter and cause an infection.

Moisture

Excessive moisture can also cause paronychia. This can include wetting the hands or feet too often, or wearing tight-fitting shoes or gloves that trap moisture. This can create an environment that is conducive to bacterial, fungal, or yeast growth, which can lead to an infection.

Getting a Diagnosis

Signs and Symptoms

The most common signs and symptoms of paronychia include redness, swelling, and pain around the nail. The area may also be warm to the touch and may have pus or other discharge. In some cases, the nail may become discolored or brittle.

Diagnostic Tests

In order to diagnose paronychia, a doctor or nurse practitioner may take a sample of the fluid from the affected area and send it to a laboratory for testing. This can help determine the type of infection and the best course of treatment. In some cases, a doctor may also order an X-ray or other imaging tests to rule out other conditions.

Treatment

Treatment for paronychia typically involves antibiotics or antifungal medications. In some cases, a doctor may also recommend draining the area or removing the nail. In severe cases, surgery may be necessary. It is important to follow the doctor's instructions for treatment to ensure the infection does not spread or worsen.

Questions for Your Doctor

Symptoms

Describe your symptoms to your doctor. This includes any pain, redness, swelling, or discharge from the affected area. Be sure to tell your doctor if you have any other medical conditions, such as diabetes, that may make you more prone to paronychia.

Treatment

Your doctor will likely prescribe antibiotics to treat the infection. They may also recommend soaking the affected area in warm water and applying an antibiotic ointment. In some cases, your doctor may need to surgically drain the infection.

Prevention

Your doctor may recommend ways to prevent paronychia from occurring in the future. This may include avoiding activities that can cause trauma to the nails, such as biting or picking at them. Your doctor may also recommend wearing gloves when doing activities that involve water or chemicals.

Follow-up

Be sure to ask your doctor when you should return for a follow-up appointment. This is important to ensure that the infection has been completely treated and to monitor for any signs of recurrence.

Treatment

Antibiotics

Antibiotics are often prescribed to treat paronychia. These medications can be taken orally or applied directly to the affected area. Oral antibiotics are usually prescribed for more severe cases of paronychia, while topical antibiotics are used for milder cases. Common antibiotics used to treat paronychia include amoxicillin, cephalexin, and clindamycin.

Antifungal Medications

If the infection is caused by a fungus, antifungal medications may be prescribed. These medications can be taken orally or applied directly to the affected area. Common antifungal medications used to treat paronychia include clotrimazole, miconazole, and terbinafine.

Home Remedies

In addition to medications, there are several home remedies that can be used to treat paronychia. Soaking the affected area in warm water several times a day can help reduce pain and swelling. Applying a warm compress to the area can also help. Applying a mixture of equal parts vinegar and water to the affected area can help reduce the infection. Finally, keeping the affected area clean and dry can help prevent the infection from spreading.

Drugs & Medications

Drugs for Paronychia

Treatment for paronychia depends on the cause of the infection. Antibiotics may be prescribed to treat bacterial infections. Antifungal medications may be prescribed to treat fungal infections. Topical corticosteroids may be used to reduce inflammation and pain. In severe cases, surgery may be necessary to remove the infected tissue.

Preventing Paronychia

The best way to prevent paronychia is to keep the skin around the nails clean and dry. Avoid biting or picking at the nails, and wear gloves when working with chemicals or cleaning products. If you have a cut or sore on your finger, keep it clean and covered with a bandage.

Lifestyle

Keep Your Nails Clean and Dry

Keeping your nails clean and dry is one of the best ways to prevent paronychia. Make sure to wash your hands and feet regularly with soap and water, and dry them thoroughly. Avoid using harsh soaps or detergents that can irritate the skin. Also, avoid soaking your hands or feet in water for long periods of time, as this can soften the skin and make it more susceptible to infection.

Trim Your Nails Regularly

Trimming your nails regularly can help prevent paronychia. Make sure to trim your nails straight across and not too short. This will help keep the skin around the nails from becoming irritated or damaged. Also, avoid cutting or picking at the cuticles, as this can also lead to infection.

Wear Protective Gloves

Wearing protective gloves when doing activities such as gardening or cleaning can help prevent paronychia. Make sure to choose gloves that fit properly and are made of a material that will not irritate the skin. Also, make sure to change your gloves regularly and wash your hands after removing them.

Avoid Biting Your Nails

Biting your nails can increase your risk of developing paronychia. Biting your nails can damage the skin around the nails, making it more susceptible to infection. If you have a habit of biting your nails, try to find ways to break the habit, such as keeping your nails trimmed short or wearing gloves when you feel the urge to bite.

See a Doctor if Symptoms Persist

If you have any signs or symptoms of paronychia, such as redness, swelling, or pain around the nails, see a doctor. Your doctor can diagnose the condition and recommend treatment, which may include antibiotics or antifungal medications. In some cases, surgery may be necessary to remove the infected tissue.
