Hello. I am a healthy, active person. A little over a year ago I got a concussion, with no litigation concerns. The one symptom that I am most curious about is brain fluttering. I notice it more when I am waking up. I d also like to return to a strenuous workout, but fatigue, dizziness, and head buzzing symptoms worsen when I push it. Any answers or education to be offered? I m really wanting to get back to life.
