Hello all. I was in a car accident on 12/07/2013. Cat scan negative. Diagnosed woth a minor concussion. Its been 3 weeks to the day and I still feel foggy. I can't seem to shake that one symptom. My primary doctor said I have post concussion syndrome. He said this foggy feeling can last 6 weeks or so. Wheb I asked if there was something I cam do to make it feel better he said no. I just need time to heal. Does anyone know if vitins help with the fogginess or is there something you cam do to relieve it at all. Thanls!!!
