Hello and welcome to HCM i have gone through your query. Sore throats commonly caused by a viral infection but bacterial infection may also cause a sore throat like : Strep throat, which usually does not occur with congestion or a cough. An inflammation or infection of the tonsils (tonsillitis) and sometimes the adenoids (adenoiditis). An infection of the tissues around the tonsils (peritonsillar abscess). Inflammation of the epiglottis (epiglottitis). The treatment for a sore throat depends on the cause as for a sore throat caused by viral infection you don t need to take antibiotics but for bacterial infection you do. However, you can treat many sore throats at home. ~ gargling with warm salt water ~ drinking plenty of warm fluids, such as teas, soup, and water ~ avoiding allergens and irritants, such as smoke and chemicals ~ taking throat lozenges ~ reducing inflammation with ibuprofen or acetaminophen (paracetamol) if the symptom persist then you should visit a doctor. Hope this answers your query. Regards Dr. Shesh
