Throat Infection:

 Pharyngitis is an inflammation of the throat or pharynx. In most cases it is painful, and thus is often referred to as a sore throat. It can result in very large tonsils which cause trouble swallowing and breathing. Some are accompanied by a cough or fever.

Most cases are caused by viral infections (40%-60%), with the remainder caused by bacterial infections, fungal infections, or irritants such as pollutants or chemical substances. Treatment of viral causes are mainly symptomatic while bacterial or fungal causes may be amenable to antibiotics and anti-fungals respectively
