I have been having weird symptoms for over 2 years now. I have been experiencing dull head pressure 24/7 jittery feeling, like being anxious. Right arm and leg gets weak off and on, and clicking noise when I turn my head from side side. My right eye has pressure a lot, because I did get hit with a softball my freshman year of high school but that was years ago. I had a cat scan two years ago, and it came back normal. I am worried about possible brain tumors or something. Roshaunda Hayes
