Hello doctor, For a month I have been suffering from a wide range of symptoms. Anything including, bad headaches, pressure and burning sensations in my brain, taste of blood in my mouth, off balance and dizzy, fatigue, and now cold feet and hands constantly. I m nervous and scared. What is going on.. I play soccer and I am known to head the ball an awful lot.. My Dr says it s nothing but post concussion syndrome. I believe its more than that...
