Went to market on Friday noon ate dinner at 10 and then got chakkkar and lied on bed and then had vomiting, then I slept and next day i.e on Saturday I ate daliya and khichdi only and took rest for full day but can feel right hand has Little weakness and pain at back of head and neck. On Sunday took rest but felt same like on Saturday. Today i.e Monday got up on time and started with regular routine but can feel little weakness in right hand but no headache. What could be possible cause also I was sleeping late around 3am and getting up at 8:30 am for last 2 months or so.
