A fluid-like bump near the fingernail cuticle could be a sign of paronychia, a common skin infection. It is usually caused by an injury to the area, such as biting or picking at a hangnail, or from trimming or pushing back the cuticle. Paronychia typically presents as a swollen, red, and painful area around the nail, sometimes with a visible collection of fluid or pus. Another possible cause of a fluid-like bump near the fingernail is a myxoid cyst, which can leak a sticky fluid when injured.

What You'll Learn
Paronychia, a skin infection around the nails
Paronychia is a skin infection around the nails that can affect both the fingernails and toenails. It is caused by bacteria or fungi entering broken skin near the cuticle and nail fold, resulting in an infection. The cuticle is the skin at the base of the nail, and the nail fold is where the skin and nail meet. Paronychia can develop due to various reasons, including trauma, irritation, or injury to the nail bed or cuticle area. This can be caused by accidents, nail biting, frequent manicures or pedicures, or certain medications.
The main symptoms of paronychia include a painful, red, swollen area around the nail, often accompanied by pus-filled blisters. These symptoms usually develop over several hours or days but can sometimes take longer. In some cases, the infection can cause the nail to become detached, abnormally shaped, or discoloured.
To treat paronychia, it is recommended to soak the infected area in warm water several times a day to reduce pain and swelling. Antibiotics may be prescribed to kill the bacterial infection, and pus may need to be drained from the wound. In some cases, the fluid causing the infection may be sent to a laboratory to determine the specific type of bacteria or fungus responsible.
To prevent paronychia, it is important to avoid damaging the nails or cuticles and to keep the nails trimmed and smooth. Avoiding nail biting and picking is crucial, as it can create tiny cracks in the nails or cuts in the skin, allowing bacteria to enter. Additionally, using rubber or plastic gloves when working with detergents, chemicals, or water can help protect the nails and reduce the risk of infection.
While paronychia usually clears up with treatment, it can sometimes lead to chronic paronychia, where the infection lasts a long time or recurs. In rare cases, untreated paronychia can cause permanent damage to the nail and even result in the loss of fingers, toes, or limbs if the infection spreads. Therefore, it is important to seek medical attention if symptoms persist or worsen.

Myxoid cysts, which can leak a sticky fluid when injured
Myxoid cysts, also known as digital mucous cysts, are small, shiny, fluid-filled lumps that usually appear near a joint on the fingers or toes. They are noncancerous and often disappear on their own without treatment. However, in some cases, they may persist or cause discomfort, leading to a desire for medical treatment.
These cysts are commonly associated with underlying health conditions such as osteoarthritis, which can cause pain in the nearby joint. Myxoid cysts have a smooth, shiny surface and are usually skin-coloured, with a translucent appearance. They can range in size from 5 millimetres to 1 centimetre across and may be firm or filled with a jelly-like, sticky fluid. While they typically don't cause any pain, they can be tender if they put pressure on other structures, such as nerves.
In rare cases, myxoid cysts may grow under the nail, leading to potential nail deformities. This can cause a groove to develop down the length of the nail, along with slight depressions or colour changes. The nail may even split or be lost completely. When a myxoid cyst grows under the nail, it can leak a sticky, thick fluid called synovial fluid, which is normally present to protect joints and tendons from damage during movement. This leaked fluid may appear clear, yellowish, or pinkish.
The exact cause of myxoid cysts is not fully understood, but they are believed to be related to the degeneration of connective tissue. There seem to be two types: those linked to osteoarthritis, where the lining of the finger joint grows excessively, and those caused by unusual deposits of mucins (mucopolysaccharides) in the skin of the finger or toe. Myxoid cysts are typically diagnosed through a physical examination by a healthcare provider, who may also request imaging tests or a biopsy for confirmation, especially if the cyst is located under the nail.

Bacterial infections, which can invade injured skin
Paronychia is a bacterial infection that occurs when bacteria enter broken skin near the cuticle and nail fold, causing an infection. The cuticle is the skin at the base of the nail, and the nail fold is where the skin and nail come together. Paronychia usually results from injury to the area, such as biting off or picking a hangnail, or from trimming or pushing back the cuticle. It can also be caused by certain medications, underlying skin conditions, or exposure to irritants such as detergents and other chemicals.
The main symptom of paronychia is a painful, red, swollen area around the nail, often at the cuticle or at the site of a hangnail or other injury. There may also be pus-filled blisters, especially with a bacterial infection. The infection can cause the nail to become detached from the nail bed and fall off. In some cases, the infection lasts a long time or comes back after treatment.
Paronychia is typically treated with antibiotics to kill the infection. Providers may also drain pus (thick, infectious fluid that builds up around a wound) and culture the fluid to determine the specific bacteria causing the infection. Soaking the infected nail in warm water several times a day can help reduce swelling and pain.
To prevent paronychia, it is important to take good care of your nails and avoid injuring your nails and fingertips. Keep your nails trimmed and smooth, and avoid biting or picking your nails or cuticles. Protect your nails from exposure to detergents and chemicals by using rubber or plastic gloves.

Injuring the cuticle, e.g. by biting nails or hangnails
Biting nails, hangnails, or cutting cuticles can cause tiny cracks in the nails or cuts in the skin, leading to a bacterial or fungal infection called paronychia. Paronychia is a common nail infection that occurs when bacteria or fungi enter the skin through cuts or broken skin near the nail. It usually affects the skin at the base of the nail, known as the cuticle, or the sides of the nail.
Paronychia typically presents as a painful, red, swollen area around the nail, often at the cuticle or the site of a hangnail. There may be pus-filled blisters, especially with bacterial infections, while fungal infections tend to develop more slowly over time. In some cases, the nail may become detached, abnormally shaped, or discoloured.
To prevent paronychia, it is essential to avoid injuring the cuticle by biting nails, picking at hangnails, or cutting the cuticles too closely. Instead, nails should be trimmed regularly with clean clippers or scissors, leaving a slightly rounded edge for fingernails and a straight edge for toenails. It is also important to avoid cutting nails too short and to maintain good hand hygiene by washing hands and keeping nails clean.
If paronychia develops, it can usually be diagnosed through a simple physical examination by a healthcare provider. Treatment may include draining any pus or fluid and sending it to a laboratory to determine the specific bacteria or fungus causing the infection. Antibiotics may be prescribed, and soaking the affected nail in warm water several times a day can help reduce swelling and pain.
In summary, injuring the cuticle by biting nails, hangnails, or cutting the cuticles can create openings for bacteria or fungi to enter and cause paronychia. Preventative measures include proper nail care, avoiding nail biting, and maintaining good hand hygiene. Treatment for paronychia involves managing the infection and relieving associated symptoms.

Treatment for paronychia, e.g. trimming nails, avoiding cuticle damage
Paronychia is a bacterial or fungal skin infection that develops around the nail. It can be caused by biting or chewing the nails, but it is more common when working conditions require the hands to be frequently wet or exposed to chemicals.
To treat paronychia, it is recommended that you trim your nails regularly, especially after bathing when they are softer. Nails should be cut with a slightly rounded edge, straight across for toenails, and not too short. However, it is important to note that you should not trim your cuticles or use cuticle removers as this can damage the skin around the nail and allow germs to enter, leading to infection. Instead, use lotion on your nail fold and cuticles if your skin is dry to prevent cracking.
To treat the infection, you can soak the affected area in warm water several times a day to reduce swelling and pain. Some sources also recommend home remedies such as applying lemon and salt or magnesium sulphate paste to the infected area, although there is no scientific evidence to support these claims.
If symptoms do not improve, you should seek medical treatment. Doctors usually treat paronychia with antibiotics to kill the bacterial infection and may also drain any pus that has built up.
