Help feel spaced out then blind spots with zigzag lights, totally disorientated sweat literally pours from mainly head and face, but no headache take a Zolmitriptan tablet goes within 15mins approx. but left tired and "heady" next day just feel just as bad this is happening almost daily and l cannot pin point trigger thought it was stress as does happen then, but can also happen when chilled. Tried Fever few from H&B worked for 1 week. Want to avoid preventative medication, would like answers, asked Doctor for a brain scan but he wont refer me what can l do. Getting me down.
