Subungual Hematoma Symptoms and Signs

  • Blood underneath the nail of either a finger or toe is a subungual hematoma.
    • You will have a discoloration of red, maroon, or other dark color beneath the nail after an injury.
  • The most common symptom is intense pain.
    • Pressure generated between the nail and the nail bed, where the blood collects, causes this pain.
    • The pain may also be caused by other injuries such as a fracture (break) to the underlying bone, a cut in the nail bed, or bruising to the finger or toe itself.
