Respected user, hi I evaluated your query thoroughly. *Clinically this is Post-operative Spinal Head ache causing above said symptoms. *Calm down, don`t get panic , take due care at home : - prefer lying down position more - keep block support of woods / 2 bricks below each pillar of bed on legside so that your head is in slant position - make any movements very slowly - maintain your hydration by taking liquids ( hot coffee recommended ) at repeated intervals - consult your doctor & get physical examination for the same , he may prescribe you certain molecules containing Proton pump inhibitors , Anti- emetics , Betahistine for faster recovery. Hope this clears your query. Thanks for using Health care magic & giving me an opportunity to serve you. Wishing you fast and speedy recovery from the same. Regards dear take care.
