Since I can't tell by your spelling which one you mean, I am including information on two types of throat ailment: pharyngitis and laryngitis.
Pharyngitis is infection of the pharynx, also known as a sore throat. It is usually caused by a virus, but can be caused by bacteria such as Strep.
Laryngitis is an inflammation of the larynx or voice box, that may lead to hoarseness. It is also generally caused by a virus, but may be caused by bacteria.
