How easy is it to get a second concussion after the first? while recovering from a mild one, 5 days later i hit my head again. i felt no symptoms from my first one anymore didn't pass put or anything else but it picked a small headache back up again.

Reinjury: If you get another injury before healing from the first- it can increase your risks. That is why there is now much more concern for football players getting back into the game if they have had a recent concussion.

A concussion is an acute head injury causing altered conciousness, memory loss, or a combination. A prior concussion does not increase the risk for subsequent injuries, but may provide additive brain damage superimposed upon prior alterations.
