Tomorrow: Ha after concussion is common symptom but should be followed closely for other signs of progressive problem. Nausea, vomiting , confusion , and any focal numbness, weakness or clumsy ness buys you a ticket to the er.

YOU LIKELY HAVE: Post-traumatic headaches, but it is definitely favorable to have a negative cat scan.
