Why Do My Fingernails Swell and Hurt After Trimming? - Neurology

Share to:

Swelling and pain around the fingernail often occurs after trimming the nails?


The nails on my fingers often start to swell and become painful after I trim them.
Initially, I thought it was due to bacteria on the nail clippers, so I disinfected them with alcohol wipes, but the swelling persists.
The tissue around the nails on several fingers becomes swollen and painful.
Which specialist should I see? The tissue around the nails swells on one side, causing pain; some areas are not visibly red or swollen but hurt when touched, while others are noticeably swollen.
The swelling resolves very slowly and tends to recur easily.
What could be the cause of this?

Hello, regarding the pain beside your finger, I am not sure if it is caused by an ingrown nail.
I recommend seeking assistance from a surgeon.

The symptoms you are experiencing after trimming your fingernails, such as swelling and pain around the nail area, can be attributed to several potential causes. Understanding these causes can help you determine the appropriate course of action and whether you need to seek medical attention.

1. Nail Trauma: Trimming your nails too short or improperly can lead to trauma to the surrounding skin, known as the paronychium. This area can become inflamed and painful, leading to swelling. If the nail is cut too short, it can expose the sensitive skin underneath, which may become irritated and swollen.

2. Infection: If there is any break in the skin during the nail trimming process, bacteria can enter and cause an infection. This is particularly true if the nail clippers were not adequately sanitized, although you mentioned that you have disinfected them. Symptoms of an infection can include redness, warmth, swelling, and pain around the nail area. In some cases, pus may also be present.

3. Allergic Reaction: Sometimes, the materials used in nail care products, such as nail polish, removers, or even the metal of the nail clippers, can cause an allergic reaction. This can lead to localized swelling and pain.

4. Ingrown Nails: If the edges of the nails are trimmed too aggressively, it can lead to ingrown nails, where the nail grows into the surrounding skin. This condition can cause significant pain and swelling and may require medical intervention.

5. Underlying Conditions: Certain medical conditions, such as psoriasis or eczema, can cause changes in the skin around the nails, leading to swelling and pain. If you have a history of skin conditions, this could be a contributing factor.

Given the persistence of your symptoms and their tendency to recur, it is advisable to consult a healthcare professional. You should consider seeing a dermatologist, as they specialize in skin conditions and can provide a thorough examination of your nails and surrounding skin. They may perform a physical examination and, if necessary, order tests to rule out infections or other underlying issues.

In the meantime, here are some general care tips you can follow:
- Avoid Further Trauma: Be gentle with your nails and avoid trimming them too short in the future. Use proper nail clippers and techniques to minimize the risk of injury.

- Keep the Area Clean: Ensure that the area around your nails is clean and dry. If you notice any signs of infection (increased redness, warmth, or pus), seek medical attention promptly.

- Moisturize: Applying a gentle moisturizer to the skin around your nails can help prevent dryness and irritation.

- Avoid Irritants: If you suspect that nail products may be causing an allergic reaction, try to avoid using them until you can consult with a dermatologist.

In conclusion, while nail trimming is a common practice, it can lead to complications if not done carefully. The symptoms you are experiencing could be due to trauma, infection, allergic reactions, or other underlying conditions. Seeking the advice of a dermatologist will help you get a proper diagnosis and treatment plan, ensuring that your nails and surrounding skin remain healthy.
