Acute injuries of the head include concussion, contusion, blood collection, and fracture. Loss of memory, dizziness, and vomiting may occur. Shock and partial paralysis may also develop. This causes the brain tissues to swell. The swelling may be from blood or other fluids.
Symptoms begin from an hour to several weeks or more after a blow to the head.
Pressure on the brain may build to produce headache, nausea, vomiting, alteration of consciousness, and pupils of unequal size. Death can occur if this is not treated. Signs of fracture include bruising around the ears or eyes, drainage of fluids from the ears or nose, unequal size of pupils, and skull deformity. If any of these signs are present in an individual who has had a head injury, call 911. All Rights Reserved.
