If you are still having effects from the other day I would agree - get another opinion.

This reminds me too much of the actress, Natasha Richardson,  from NYC that suffered a concussion skiing in Quebec, said she was ok then died later.

IF you are still having symptoms 5 days later there may be something much more serious. Gunderson in LaCrosse  is a good facility.

Don't worry about being embarrassed if nothing is found - as mentioned above, get more help.

Best wishes,
