Pus coming out from under a fingernail can be a symptom of paronychia, a bacterial or fungal infection of the skin around a fingernail or toenail. Acute paronychia can cause throbbing pain, redness, warmth, and swelling in the skin around a nail, and a collection of pus may form under the skin next to the nail or underneath the nail itself.

What You'll Learn
Paronychia, a skin infection around the nail
Paronychia is an infection of the skin around a fingernail or toenail. It is usually caused by bacteria entering broken skin near the cuticle and nail fold, causing an infection. The cuticle is the thin layer of skin at the base of the nail, and the nail fold is where the skin and nail meet.
The symptoms of paronychia include pain, swelling and tenderness around the nail, as well as redness and warmth of the skin. In some cases, pus can build up under the skin, forming a white to yellow, pus-filled blister (abscess). If left untreated, the nail can become deformed, with ridges or waves, and may appear yellow or green, dry and brittle.
Paronychia can be caused by biting, chewing or picking at the nails, or by pulling hangnails. It can also be caused by an ingrown toenail, or by moisture, allowing certain bacteria and fungi to grow. People whose hands are often wet, such as bartenders and dishwashers, are at a higher risk of developing paronychia. It is also more common in people with underlying skin conditions, and in those with diabetes or vascular disease.
Mild cases of paronychia can be treated at home by soaking the infected area in warm water several times a day, which helps pus to drain. More severe cases may require antibiotics to kill the infection, and pus may need to be drained by a healthcare provider. In some cases, a pus sample may be sent to a laboratory to determine the type of bacteria or fungus causing the infection.

Symptoms of paronychia: throbbing pain, redness, warmth, swelling
Paronychia is an infection of the skin that surrounds a toenail or fingernail. It is characterised by throbbing pain, redness, warmth, and swelling in the skin around the nail. The infection may result from trauma, irritation, or bacterial infection, often caused by over-aggressive manicuring, especially when cutting or tearing the cuticle.
Acute paronychia is identified by a sudden, very painful area of swelling, warmth, and redness around the nail. It is typically caused by an infection of the skin where it has been injured. Chronic paronychia, on the other hand, usually presents less dramatic symptoms. The area around the nail is tender, red and mildly swollen, and the cuticle may be missing.
If you are experiencing throbbing pain, redness, warmth, and swelling around your nail, it is important to examine the affected area for signs of infection. Look for any pus formation, which may appear as a white or yellow fluid around or under the nail. If pus is present, it is advisable to seek medical attention, especially if the symptoms persist or worsen.
In most cases, a healthcare provider can diagnose paronychia by visually inspecting the infected area. They may take a sample of the pus to determine the specific bacteria or fungus causing the infection. Treatment options include soaking the affected area in warm water several times a day to promote pus drainage, and antibiotics to address the infection. If pus has accumulated, a medical professional may drain the pus by making a small incision and placing a bandage over the cut.

Causes of paronychia: irritation, trauma, bacteria, fungi
Paronychia is an infection of the skin around a fingernail or toenail. It is caused by bacteria or fungi that get under the skin through cuts in the cuticle and the nail fold (the skin around the nail). The infection can occur spontaneously or following trauma or manipulation.
Irritation
Irritation from detergents and other chemicals can irritate the skin and lead to a nail bed infection. People who work with chemicals and don't wear protective gloves are at a higher risk. Frequent hand washing can also be a risk factor for paronychia.
Trauma
Trauma to the cuticle or nail fold can also cause paronychia. This can be caused by relatively minor events such as dishwashing, an injury from a splinter or thorn, nail biting, biting or picking at a hangnail, finger sucking, an ingrown nail, or manicure procedures.
Bacteria
Bacteria, such as Staphylococcus aureus, can invade the skin through cuts or breaks in the skin, causing an infection. This is known as acute paronychia and usually appears as a sudden, very painful area of swelling, warmth, and redness around the nail.
Fungi
Gradual or chronic paronychia is typically caused by fungi, commonly Candida albicans. It is often seen in people whose hands or feet are subject to moist local environments and can be due to contact dermatitis.

Diagnosis: physical examination, pus sample, laboratory testing
If you notice pus coming out of your fingernail, it is best to seek medical advice from a healthcare provider. The provider will ask about your symptoms and conduct a physical examination. They will visually inspect the affected area for any signs of nail inflammation, including redness, swelling, tenderness, and warmth around the nail. They will also look for any abnormalities in the nail, such as discolouration, ridges, or brittleness.
During the physical examination, the healthcare provider will determine if further diagnostic tests or procedures are necessary. In some cases, they may take a pus sample by obtaining a nail clipping or a swab of the infected area. This sample will be sent to a laboratory to test for specific infectious causes, such as bacteria or fungi. The lab tests will help identify the particular type of bacteria or fungi causing the infection.
Laboratory testing is particularly important when the cause of the infection is unclear or when there is a concern about antibiotic resistance. By culturing the pus sample, healthcare providers can identify the specific organism causing the infection and determine the most effective treatment. This process is crucial for tailoring the treatment plan to the specific type of bacteria or fungi present.
In severe or complicated cases of infection, additional imaging tests may be ordered. For example, an X-ray may be necessary to assess the involvement of the underlying bone. This step is usually reserved for cases where the infection is suspected to have spread beyond the nail itself.

Treatment: antibiotics, pus drainage, soaking infected area
Pus coming out of your fingernail could be a sign of paronychia, a bacterial or fungal skin infection that develops around the nail. It is caused by biting or chewing nails, frequent exposure to water or chemicals, or trauma to the nail bed or cuticle area.
Treatment
If you suspect you have paronychia, you should visit a healthcare professional. They will ask about your symptoms and conduct a physical examination. If the infection is severe, imaging such as an X-ray may be ordered to check for bone involvement.
Healthcare providers treat paronychia with antibiotics to kill the infection. They may also drain the pus through a procedure called the incision and drainage method. A local anaesthetic is provided, then the nail fold is opened enough to insert gauze and help drain the pus. A bandage is then placed over the cut, which should be kept clean and dry.
In mild cases, paronychia can be treated at home by soaking the infected area in warm water for about 15 minutes a few times a day. Be sure to dry the area thoroughly. Soaking the cuticle and nail bed can help pus drain from under the skin. You can also apply lemon and salt to the affected area, although there is no scientific evidence to support this method.
To prevent paronychia, it is important to maintain good hand and nail hygiene. Avoid biting or chewing nails and cuticles, and be careful not to cut your nails too short. If your skin is dry, use lotion on your nail folds and cuticles.

Frequently asked questions
Pus is coming out of your fingernail because you have an infection called paronychia. It is a skin infection around a toenail or fingernail.
You can treat mild cases of paronychia at home by soaking the infected area in warm water for about 15 minutes a few times a day. You can also minimise germ exposure and frequently wash the infected area.
If the infection is very painful, doesn't get better with home care, or has a pus-filled abscess, you should see your doctor. If you are diabetic, have several affected fingers or toes, or have severe symptoms, you must be evaluated by a doctor.
