Hi.. Thanks for the query.. Severe sore throat and cough can be due to upper respiratory tract infection.. It is commonly viral infection but there can be secondary bacterial infection.. So my suggestion to you to first of all get a throat swab culture done.. It will help in ruling out the exact nature of infection and strain of the organisms involved.. You can be advised a course of antibiotics like Augmentin, Azithromycin etc.. Anti inflammatory painkillers like Ibuprofen can be advised.. Along with it cough suppressants like Dextromethorphan can be advised.. Do warm saline gargles, steam inhalation and use a humidifier in your room. Drink plenty of warm water.. Avoid spicy and chilled foods.. Take sufficient rest.. Hope this helps.. Regards.
