Thanks for posting your query.
You are most likely suffering from common cold
(acute flu fever), and most likely involving your liver causing vomiting
All these disease are most of the times because of virus and persist for 3-4 days. You have to take medicines for getting relief from these symptoms
You should consult with physician and get treatment for common cold.
You should also go for chest x ray, complete blood count
, liver function test, serum amylase
Get well soon,
