Hi thanks for contacting health care magic... Noted you have flu like symptoms... Sore throat , cold etc... It may be viral or allergic infection.... Symptomatic management done... For cold decongestent taken like oxymetazoline.... If it seems pure allergic and if feel by doctor he might prescribe you azelestine antihistaminic nasal spray .... Cetrizine also useful.... I would like to suggest you to do your CBC . If lymphocytosis viral and if eosinophilia allergic could be cause.... Drink more water.... Steam inhalation useful.... Avoid excess spicy food... You will recover within few days.... If still not improving then according to your physical examination further work up will decided.... Take care... Dr.Parth
