Hello, I went through your query, don't worry it is upper respiratory tract infection, due to weather change. All you need to take is paracetamol and cetrizine as a symptomatic relief, avoid cold food and drink, drink some hot tea, do salt water(warm) gargling three times a day. in case there is yellow discharge from nose or sputum is yellow and fever increases you need to take antibiotic too, please consult general physician for prescription.
