Nail Lifting: Causes and When to Seek Medical Advice

Lifted nail edge?

Hello doctor, a few days ago I developed a large blister on my thumb, and there was also a small one under the nail, measuring about 1 to 2 centimeters.
After the doctor treated it, that area is now a bit black and purple.
Is this because the dead skin at the tip of the nail is causing it to lift slightly? Do I need to see a doctor again?

Without actually seeing the lesion, it is difficult to make a definitive assessment.
If you are very concerned, please seek medical attention as soon as possible.
It is advisable to consult the physician who originally evaluated you.

More Info

Nail lifting, also known as onycholysis, can be a concerning condition that may arise from various causes, including trauma, infection, or underlying health issues. In your case, it sounds like you experienced a significant injury to your thumb, which resulted in a blister beneath the nail and subsequent discoloration. The black and purple appearance you describe could indicate bruising or bleeding beneath the nail, which is often a result of trauma.

When a nail is subjected to trauma, such as a heavy object falling on it or excessive pressure, it can lead to the separation of the nail from the nail bed. This separation can cause the nail to lift, and if there is bleeding or fluid accumulation, it may appear dark or discolored. The presence of dead skin at the front of the nail can also contribute to the lifting, as it may not adhere properly to the nail bed.

It is essential to monitor the situation closely. Here are some signs that indicate when you should seek medical advice:
1. Increased Pain: If the pain worsens or becomes unbearable, it may indicate an infection or more severe injury.

2. Signs of Infection: Look for symptoms such as increased redness, swelling, warmth around the nail, or pus discharge. These are signs that an infection may be present, and prompt medical attention is necessary.

3. Persistent Lifting: If the nail continues to lift or if the discoloration spreads, it may require further evaluation to determine the underlying cause.

4. Changes in Nail Growth: If you notice abnormal growth patterns in the nail, such as ridges or changes in thickness, this could indicate a more significant issue that needs to be addressed.

5. Underlying Health Conditions: If you have any underlying health conditions, such as diabetes or circulatory issues, it is crucial to consult a healthcare professional, as these conditions can complicate healing and increase the risk of infections.

In your specific case, since you have already seen a doctor who treated the initial injury, it may be wise to follow up if you notice any of the above signs or if you have concerns about the healing process. A healthcare professional can assess the nail and surrounding tissue, provide appropriate treatment, and advise on care to promote healing.

In summary, nail lifting can occur due to trauma, and the discoloration you see may be related to the injury. Keep an eye on the symptoms, and do not hesitate to seek medical advice if you experience increased pain, signs of infection, or any other concerning changes. Proper care and monitoring are essential to ensure the best outcome for your nail health.
