Painful Bumps Near Your Fingernail: When to See a Dermatologist - Dermatology

Pimples on fingers???


Hello, Doctor! About two days ago, I noticed a red, swollen bump resembling a pimple next to the skin beside my left middle fingernail.
It has a white substance inside that looks like pus.
It doesn't bother me unless I press on it, and pressing it causes pain.
There are no visible wounds nearby, and I'm not sure if it's an infection.
A few days ago, I did trim my nails, but I didn't cut into the skin.
What could this condition be? Will it resolve on its own if I leave it alone, or should I see a dermatologist? Thank you for taking the time to respond!

I'm sorry, but online diagnoses are not permitted.
If you are truly troubled, please visit a dermatologist or a surgical outpatient clinic in person.

More Info


It sounds like you are experiencing a painful bump near your fingernail, which can be concerning. Based on your description, it seems like you may have developed a condition known as a paronychia, which is an infection of the skin around the nail. This can occur when bacteria or fungi enter through a break in the skin, often exacerbated by activities such as nail trimming or biting. The presence of a red, swollen bump with white pus suggests that there may be an infection present.

Paronychia can be acute or chronic. Acute paronychia typically arises suddenly and is often caused by bacteria, while chronic paronychia can develop over time, usually due to a fungal infection or repeated exposure to moisture. In your case, since you mentioned that you recently trimmed your nails, it is possible that the skin was slightly damaged, allowing bacteria to enter and cause an infection.

In terms of treatment, if the bump is not causing significant pain or discomfort and is not growing, it may resolve on its own. However, if you notice increasing redness, swelling, or pain, or if the pus-filled bump does not improve within a few days, it is advisable to seek medical attention. A dermatologist can assess the situation more thoroughly and may recommend drainage of the pus if necessary, along with antibiotics if a bacterial infection is confirmed.

In the meantime, here are some general care tips you can follow:
1. Keep the Area Clean: Gently wash the affected area with soap and water to reduce the risk of further infection.

2. Avoid Squeezing: Do not attempt to squeeze or pop the bump, as this can worsen the infection or push bacteria deeper into the skin.

3. Warm Compresses: Applying a warm compress to the area can help reduce swelling and promote drainage if there is pus.

4. Avoid Irritants: Try to keep the area dry and avoid exposing it to irritants, such as harsh soaps or chemicals.

5. Monitor Symptoms: Keep an eye on the bump for any changes. If it becomes increasingly painful, red, or swollen, or if you develop a fever, seek medical attention promptly.

In conclusion, while it is possible that the bump may resolve on its own, it is essential to monitor your symptoms closely. If there is no improvement or if the condition worsens, visiting a dermatologist would be the best course of action. They can provide a proper diagnosis and treatment plan tailored to your specific situation. Remember, early intervention can prevent complications and promote faster healing.
