Welcome to NeuroTalk

Did you sense any IMMEDIATE dazed and confused sensation, just for a second?

If not, then, NO, this was not a concussion.

It is very difficult to get a concussion without a head impact. A seat belt concussion, where you are thrown against your seat belts in a sudden car collision stop would also cause an injured sternum/chest and serious whiplash. Even then, most of the concussion would be a cervical (upper neck) concussion.

A shoulder bump is not enough to cause such a cervical concussion.

A simple question.

If I or anybody said this could have been a concussion, what would you do about it?

There is NO general treatment for a concussion.
