What could a red dot under my nail suggest?
A red dot under your nail could be caused by various conditions, including minor injuries or more serious issues like nail infections or growths.
Explanation
A red dot under the nail can have different causes. It might be something simple like a small injury or bruise, which can happen if you accidentally hit your nail. Sometimes, infections can also cause changes in nail color. In rare cases, it might be related to a growth or changes in the skin cells under the nail.
Possible Causes:
- Minor Injuries: These are common and can occur if you bump or hit your nail, causing a small bruise.
- Infections: Sometimes, infections can lead to changes in the color of the nail or the skin underneath.
- Nail Growths: In certain cases, changes in the skin cells under the nail could lead to discoloration.
If the red dot doesn't go away or changes in size or shape, it's a good idea to have it checked by a healthcare professional. They can determine if it's something that needs treatment or if it's harmless.
