Do the symptoms come and go for no apparent reason? My son has had several days of rest and was doing better but suddenly tonight after watching basketball on TV, he is pretty dizzy and with a worsening headache. Is it 2 steps forward and three steps back sometimes? He seems to be in his own personal hell. It may be because I had to leave him alone all day to work. He may do worse if he gets lonely. Sorry, just randomly thinking to no one in particular. I am obviously frustrated that nothing can be done but watch it.
