Blood Under the Nail Overview
Another name for Blood Under the Nail is Subungual Hematoma.
What is a subungual hematoma?
A person with a subungual hematoma has a collection of blood under a fingernail or toenail. In most cases, this occurs after an injury to the fingertip or toe tip. Bleeding under the nail can cause intense pain.
What are the symptoms of a subungual hematoma?
Symptoms of a subungual hematoma include a collection of blood or a bruise beneath the nail. A large subungual hematoma may cause severe pain beneath the nail.
How does the doctor treat a subungual hematoma?
Subungual hematomas do not require treatment if they do not cause pain. Treatment for a painful subungual hematoma includes creating a hole in the nail, in order to allow the blood to drain from beneath the nail. This procedure is called trepanation, and it may be performed with a very tiny drill, or a needle.
