Head trauma is an injury to the head when, for example, you fall and hit your head or something hits you in the head. Sometimes you may be hit hard enough that you have a concussion, which is an injury to the brain caused by a blow to the head. Minor, or less serious, head trauma does not cause a concussion.
Even minor head trauma can be quite painful. The face and scalp are more sensitive than most of the other parts of the body. The head has a rich blood supply so that even a small cut to the face or scalp may bleed a lot. As blood collects under the skin, you may have a large swollen area where the blood clots. This isn't dangerous and it goes away in a week or two.
The symptoms of a more serious injury, such as a concussion, are:
If you are concerned that you may have suffered a more serious head injury or a concussion, contact your health care provider or go the nearest emergency department to be checked.
Your health care provider will ask about how you hurt your head and examine you. He or she will check for signs or symptoms of a more serious injury, such as a concussion.
If you cut your head and the cut is very long or deep, it may need stitches. You may also need a tetanus shot, depending on how you were injured and when you had your last shot.
You can take acetaminophen or ibuprofen for pain if you don't have a medical reason for not taking these drugs. Don't take aspirin because it may make the bleeding worse. Don't take any pain medicines that might make you sleepy or confused (like narcotics or sedatives such as Valium) unless you take these medicines regularly for another medical problem. The effects of these drugs might be confused with signs of a concussion.
After minor head trauma the headache may last for a few hours. You may have swelling or a bruise for a week or two.
