My 18 year old daughter was injured on the job receiving a grade 3 concussion on april 1st. Today is April 25th. She's received 2 ct scans that show no bleeding but do show swelling. She's still suffering some pretty severe symptoms such as dizziness, headache, lethargy and nausea. We can't get into a neurologist until May 8th. I know the symptoms can last for quite sometime but in the mean time are there things they can check to make sure something worse isn't underlying? What can I expect the neurologist to check for or do?
