Nail lifting


Hello, my left/right toenail is separating from the nail bed for no apparent reason, but it hasn't completely detached from my little toe; only a corner is still attached.
It doesn't hurt and seems to be dead, but I'm very worried.
Could ill-fitting shoes cause this issue? How should I handle it? I'm afraid that if the nail is removed, it might get infected.
My part-time job often involves water, and I have a habit of wearing sneakers.
Will covering my toe cause it to rot? Thank you for your assistance and advice!

Dr. Huang Junxiong reply Surgery


It is recommended that you consult a general surgeon, who will assess whether it is necessary to remove the remaining nail.
The toe without a nail should be kept dry and protected from water until the wound has healed.

More Info


Nail separation, also known as onycholysis, can be a concerning condition, especially when it occurs without an obvious cause. It is characterized by the separation of the nail from the nail bed, and while it may not be painful, it can lead to other complications if not properly managed. Let's explore the potential causes, concerns, and care tips for this condition.


Causes of Nail Separation
1. Trauma: One of the most common causes of nail separation is trauma to the nail. This can occur from stubbing your toe, wearing ill-fitting shoes, or repetitive pressure on the nails. If you frequently wear tight shoes or engage in activities that put stress on your toes, this could be a contributing factor.

2. Fungal Infections: Fungal infections can lead to nail separation. If you notice discoloration, thickening, or crumbling of the nail, it may be a sign of a fungal infection that requires treatment.

3. Psoriasis: This skin condition can also affect the nails, leading to separation. If you have a history of psoriasis, this could be a potential cause.

4. Chemical Exposure: Frequent exposure to harsh chemicals, such as those found in cleaning products or nail polish removers, can weaken the nails and lead to separation.

5. Underlying Health Conditions: Certain health issues, such as thyroid disorders or nutritional deficiencies (like a lack of biotin), can affect nail health and lead to separation.


Concerns with Nail Separation
While nail separation may not be painful, it can lead to several concerns:
- Infection: The space created by the separation can become a breeding ground for bacteria and fungi, leading to infections. Signs of infection include redness, swelling, pus, or increased pain.

- Nail Damage: If the nail continues to separate, it may eventually fall off, which can be distressing and may take a long time to regrow.

- Aesthetic Concerns: Many people are concerned about the appearance of their nails, and separation can be unsightly.


Care Tips for Nail Separation
1. Keep It Clean and Dry: Since you mentioned that your job involves frequent exposure to water, it's crucial to keep the affected area clean and dry. After washing your hands or feet, ensure they are thoroughly dried, especially around the nail area.

2. Avoid Irritants: Try to avoid exposing your nails to harsh chemicals. If you must use them, consider wearing gloves to protect your nails.

3. Wear Proper Footwear: Ensure that your shoes fit well and provide adequate support. Avoid tight or ill-fitting shoes that can cause trauma to your nails.

4. Moisturize: Keeping the nail bed moisturized can help prevent further separation. Use a gentle moisturizer on your feet and nails.

5. Consult a Healthcare Professional: If the separation persists, worsens, or shows signs of infection, it’s essential to consult a healthcare professional. They can assess the condition, determine the underlying cause, and recommend appropriate treatment. This may include antifungal medications if an infection is present or other treatments based on the diagnosis.

6. Avoid Self-Removal: Do not attempt to remove the nail yourself, as this can lead to further injury and increase the risk of infection. If the nail is severely damaged, a healthcare professional can safely remove it if necessary.

In conclusion, while nail separation can be concerning, understanding the potential causes and taking appropriate care can help manage the condition effectively. If you have ongoing concerns or if the situation worsens, seeking medical advice is always the best course of action.
