Nail Trauma: Growth Stoppage and Pain After Injury - Dermatology

More Info

---

Nail trauma, particularly in athletes, can lead to various complications, including pain, growth stoppage, and changes in nail appearance. In your case, the history of trauma to your left big toe's nail, combined with the use of improperly fitting shoes, suggests that you may be experiencing a condition known as subungual hematoma or possibly nail matrix damage.

When you mentioned that your toenail cracked after switching to new basketball shoes, it indicates that the trauma could have caused damage to the nail matrix, which is the tissue under the base of the nail responsible for nail growth. If the nail matrix is injured, it can lead to abnormal nail growth or even cessation of growth altogether. The pain you feel upon pressing the nail root could be due to inflammation or pressure from the nail bed or surrounding tissues.

The fact that your toenail has not grown in length for two months and appears to be retracting suggests that there may be ongoing issues with the nail matrix. The U-shaped appearance of the nail bed could indicate that the nail is being pushed back due to swelling or other changes in the underlying tissue.

Here are some recommendations for managing your condition:
1. Consult a Specialist: It's essential to see a podiatrist or dermatologist who specializes in nail disorders. They can assess the extent of the injury and determine if there is any underlying damage to the nail matrix.

2. Avoid Further Trauma: Until you receive a professional evaluation, it's crucial to avoid activities that may further injure the toe, such as playing basketball or wearing tight shoes. Opt for open-toed footwear or shoes with a wide toe box to reduce pressure on the affected area.

3. Pain Management: If you're experiencing pain, over-the-counter pain relievers like acetaminophen or ibuprofen can help alleviate discomfort. However, consult with a healthcare professional before taking any medication, especially if you have underlying health conditions.

4. Nail Care: Avoid any further cosmetic treatments on the nail until the condition stabilizes. This includes refraining from nail reconstruction or artificial nails, as these can exacerbate the problem.

5. Monitor for Changes: Keep an eye on the nail's appearance and any changes in pain levels. If the pain worsens or if you notice signs of infection (such as increased redness, swelling, or discharge), seek medical attention promptly.

6. Consider Nail Surgery: In some cases, if there is significant damage to the nail matrix or if the nail continues to grow abnormally, surgical intervention may be necessary to remove the damaged nail or to repair the matrix.

7. Rehabilitation: Once the acute phase has passed, and if the nail matrix is intact, gentle exercises to improve circulation and flexibility in the toe may help promote healthy nail growth.

In summary, while nail trauma can lead to complications, proper evaluation and management can help mitigate long-term effects. It's crucial to prioritize your foot health, especially as an athlete, to prevent further injuries and ensure optimal recovery.
