my girlfriend has been having horrible headaches every single day nonstop for at least a week now. on a scale of 1-10 she says there at a 7 or 8 at times. she has lost her appatie to eat, she's constantly dizzy. the doctors put her on a medicine that would have made the headaches go away but it didn't instaed it made her symptoms worst, and her foot went numb. does anyone have any idea whats wrong? Her CT scan came back normal.
