Symptoms of a hematoma generally depend on its size and location. Irritation, pain, swelling, redness, and disfiguring bruises are common symptoms of hematoma in general. Some symptoms specific to the location of a hematoma are:
Subdural hematoma: headache, neurologic problems (weakness on one side, difficulty speaking, falling), confusion, seizures
Epidural hematoma: back pain, weakness, loss of bowel or bladder control
Subungual hematoma: nail pain, nail weakness, nail loss, disfiguring nail
- Splenic, hepatic, or peritoneal hematoma: abdominal pain, flank pain
Sometimes there are not any symptoms at all associated with even a very large hematoma.
Hematomas are usually caused by trauma, whether it is the result of a car accident, a minor bump, a cough, or an unknown event.
