Thanks for writing to H.C.M.for your query.
I have gone through your query regarding running nose, sore throat
, cough and nausea. Your all are these symptoms are related to each other. Due to nasal infection
as you feel running nose infection reached to throat and thus there developed soreness in throat, throat infection
is responsible for cough, and frequent cough
initiates the nausiating tendency.
To manage it you should take-
(b) Anti inflammatory.
(c) Anti allergic and decongestant.
(d) Steam Inhalation.
I hope this will help you , but unfortunately if you feel no responce than than thorough examination and relevent investigations will necessary.
