Hi thanks for contacting HCM.. Here according to history you are having acute viral infection.... It might be in form of pharyngitis or rhinitis ... Drink lots of fluid..... Avoid excess spicy food.... Fried food less. Salt water gargles done .... For congestion relief take antihistaminic like dimenhydrinate 50 mg in morning and evening after meal.... If headache more you can take paracetamol like analgesic sos.... If still no benefit then bronchitis ruled out by chest x ray and posterior pharynx swab taken. For that consultation to physician done. Hope your concern solved.
