I don t have any history of headaches, but for the past two weeks I ve had one constantly. In the past week, I ve been seeing black spots and moving things, I hear different things, and I m smelling different things. My mind has seemingly taken a turn for the worse, too. I can t focus (but I ve already gotten diagnosed with ADD), I have blackouts of memories that I once remember remembering and now I can t think of them at all (both past and recent), I can t follow along with directions or learn things as easily as I once could. Mind you, I m 19 years old. I was ordered to go immediately to have a ct scan done, but they told me it was fine. Any help?
