Symptoms

Head injuries may cause bleeding in the brain tissue and the layers that surround the brain (subarachnoid hemorrhage, subdural hematoma, epidural hematoma).

Symptoms of a head injury can occur right away or may develop slowly over several hours or days. Even if the skull is not fractured, the brain can hit the inside of the skull and be bruised. The head may look fine, but problems could result from bleeding or swelling inside the skull.
