Bleeding under your nails, often called a subungual hematoma, usually happens due to an injury. Small blood vessels under the nail (nail bed) called capillaries burst, causing blood to leak and become visible through the nail. This is sometimes referred to as a splinter hemorrhage when the bleeding appears as thin red lines.
Common Causes of Bleeding Under the Nails:
- Trauma: The most frequent cause is an injury like stubbing a toe, hitting a finger, or a forceful impact to the nail. This damages the capillaries under the nail, leading to bleeding. (Source: Cleveland Clinic, WebMD, Healthline)
- Nail procedures: Rough handling during manicures or pedicures, especially when using tools like drills, can sometimes cause minor cuts and bleeding. (Source: Reddit discussion: https://www.reddit.com/r/RedditLaqueristas/comments/ygvd2e/how_often_do_you_have_bleeding_around_your_nail/)
When to See a Doctor:
While minor bleeding often resolves on its own, consult a doctor if:
- The bleeding is severe or accompanied by significant pain.
- The affected area shows signs of infection (swelling, pus, increased pain).
- The bleeding doesn't stop after applying pressure.
- You experience repeated episodes of bleeding under your nails.

Further Considerations:
In rare cases, repeated or unexplained bleeding under the nails might indicate an underlying medical condition. It's crucial to consult a healthcare professional for proper diagnosis and treatment if you have concerns. (Source: Cleveland Clinic)
