Should i worry about light head bump against another head while recovering from a concussion?

Below: IF you have any symptoms similar to when you had the concussion, then you need evaluation. Usually a light head bump will not cause problems.

Not likely: If it is a light bump and no further symptoms occur it should not be an issue. Obviously it would be best to avoid further injury but if it does happen you should get re-evaluated.

Want to limit: Any hard impacts with the head are of some concern post concussion. But if you did hit your head and did not experience immediate concussive effects, I wouldn't dwell on it.
