Pain under the fingernail?


Hello Doctor: I have pain in the area just below the nail of my ring finger, near the tip.
The external appearance of my finger shows only a slight redness under the nail bed, with no swelling or pus.
However, the redness is very subtle and can only be noticed when compared to my other fingers.
The pain comes and goes, whether I press on it or leave it alone, and at times it has been severe enough to prevent me from sleeping.
I consulted a dermatologist who diagnosed it as paronychia and prescribed medication for three days, but there has been no improvement; in fact, the pain has worsened.
I then thought I might have seen the wrong specialist and visited a family medicine doctor, who suggested it might not be paronychia since the location is different, but he was unsure which specialty could address this issue.
Could you please advise whether I should see a dermatologist or another specialist? Thank you.

It is possible that there is a painful small tumor growing on the nail bed; it is recommended to see a dermatologist first.

More Info


Nail bed pain can be a perplexing issue, especially when it is accompanied by redness and discomfort without significant swelling or discharge. Based on your description, it seems that you are experiencing pain localized to the nail bed of your ring finger, which has been persistent and even severe enough to disrupt your sleep. Given that you have already consulted a dermatologist and a family medicine physician, it is essential to consider a few potential causes and treatment options.


Possible Causes of Nail Bed Pain
1. Paronychia: This is an infection of the skin around the nail, which can be acute or chronic. While you mentioned that there is no significant swelling or pus, the redness could indicate an early stage of paronychia. It can be caused by bacteria or fungi, and sometimes, it may not present with classic signs of infection.

2. Nail Bed Injury: Trauma to the nail bed, even if minor, can lead to pain and localized inflammation. If you have had any recent injuries or repetitive trauma to that finger, it could explain the pain.

3. Nail Psoriasis: Psoriasis can affect the nails and nail beds, leading to pain, discoloration, and changes in nail texture. If you have a history of psoriasis, this could be a contributing factor.

4. Onycholysis: This condition involves the separation of the nail from the nail bed, which can cause discomfort and pain. It can be associated with various factors, including trauma, fungal infections, or systemic conditions.

5. Systemic Conditions: Conditions such as rheumatoid arthritis or other autoimmune disorders can manifest as pain in the nail bed area. If you have other symptoms, it might be worth exploring this avenue.


Recommended Specialists
Given the complexity of your symptoms and the lack of improvement with initial treatments, it may be beneficial to see a specialist who can provide a more comprehensive evaluation. Here are a few options:
- Dermatologist: Since you have already seen a dermatologist, it may be worth returning for a follow-up or seeking a second opinion, especially if you suspect a skin condition like psoriasis or a fungal infection.

- Rheumatologist: If there are signs of systemic involvement or if you have other joint-related symptoms, a rheumatologist could help assess for autoimmune conditions.

- Orthopedic Specialist: If there is a possibility of a structural issue or injury related to the finger, an orthopedic specialist could provide insights into any underlying musculoskeletal problems.


Treatment Options
1. Topical Treatments: If the pain is due to an infection or inflammation, topical antibiotics or antifungal creams may be prescribed. If psoriasis is suspected, topical corticosteroids or other psoriasis treatments may be indicated.

2. Oral Medications: If an infection is confirmed, oral antibiotics or antifungals may be necessary. For inflammatory conditions, nonsteroidal anti-inflammatory drugs (NSAIDs) can help alleviate pain and swelling.

3. Warm Soaks: Soaking the affected finger in warm, soapy water can help reduce discomfort and promote healing, especially if there is any infection.

4. Avoiding Irritants: If you frequently expose your hands to water or chemicals, consider wearing gloves to protect your nails and skin.

5. Surgical Intervention: In severe cases, if there is significant infection or structural issues, minor surgical procedures may be required to drain abscesses or correct nail bed problems.


Conclusion
In summary, nail bed pain can arise from various causes, and it is crucial to identify the underlying issue for effective treatment. Given the persistence of your symptoms and lack of improvement, I recommend seeking a follow-up with a dermatologist or considering a consultation with a rheumatologist or orthopedic specialist. They can provide a more targeted approach to diagnosing and managing your condition. Remember to keep track of any changes in symptoms and communicate these to your healthcare provider for the best possible care.
