Hit my head on the school bus. it wasn't very painful with no symptoms but i'm concerned about a concussion. are there tests i can do myself to check.

Head Injury: If you did not become sleepy or 'somnolent' as we call it, and/or did not get nauseated or vomited, then you most likely do not have a concussion. If more than 24 hours have passed since your injury without these symptoms then you will be fine.No testing needed.

Concussion Symptoms: Most people with a concussion recover quickly and fully. But for some people, symptoms can last for days, weeks, or longer. Symptoms of concussion: thinking, remembering, emotional, sleep, difficulty thinking clearly, headache, fuzzy or blurry vision, irritability, sleeping more than usual, feeling slowed down, dizziness, sensitivity to noise or light, balance problems, more emotional, difficult.

Concussion: With a hit to the head and no symptoms such as headache, vomiting or altered mental status it is extremely unlikely you sustained a concussion.

Concussion?: If you do not have any symptoms of concussion including change in alertness or unconsciousness, headache, confusion, you have not had a concussion. There are not home tests except to keep track of symptoms and discuss them with your doctor.
