Yоur sоftbаll cаtcher cоmes to you before prаctice and complains of a headache. She said she took a hard foul ball off the facemask in practice yesterday and hasn't felt very good since. In talking to her, you find out that she has had a persistent headache since that time. Right after taking the hit, she was dizzy for about 10 minutes, but kept catching and didn't tell anyone.
