having headache since 2008, its dosnt go away . Then sometimes feels like someone hit me in head with rock . The pain was on left side of head ,now it was back of head. when the pain sharpens it causes right side to go paralyzied with drooping right side of mouth(slurred talk) ,right eye shut .These things are like a stroke. always treated as stroke when in hospital. takes weeks to months to get better . Dont ever ge to be 100% better. had cat scans mri eegs no test ever show anythings. Doc. not sure what causes this.
