You did the right thing. I am dealing w PCs from 2 very mild head injuries in last 6 weeks and have been doing some research to understand the syndrome. If you Google "2nd impact syndrome" you will see how early return to impact sports in teens can result in sudden death. This has been all the rage on the news lately since Dr Gupta has brought this information public. She should not be put at risk for a third injury this season. Gonna have to figure out some incentive to get her to understand how important it is for her to not ski for a while.
