My son went back to the concussion clinic for the second time. The doctor told me to take him back to his PCP doctor, because my son symptoms is out of his expertise and that none of his questions they asked on that sheet of paper you fill out, the score didn't go down any from the first visit. No one can tell me why my son now faints. I don't know where else to look for answers. Nobody seem to know what's wrong with him.
