Pharyngitis or sore throat is the swelling or inflammation of the back of the throat, which is known as the pharynx. This is usually the result of a sore throat and fever. Other symptoms may include a runny nose, cough, headache, and scaly noise. Symptoms usually last for 3-5 days. Complications can include sinusitis and acute otitis media. Grassitis is a type of upper respiratory tract infection.
Most cases are due to a viral infection. Strept throat, a bacterial infection, is the reason for approximately 25% of children and 10% of adults. Abnormal causes include other bacteria such as gonorrhea, fungus, smoking, allergies and gastroesophageal reflux disease. Specific tests are not recommended in those who have obvious symptoms of viral infection, such as colds. Otherwise, a Rapid Antigen Detection Test (RADT) or throat swab is advised. Other conditions that can produce similar symptoms include epiglottitis, thyroiditis, retroparency abscess, and sometimes cardiovascular disease.
NSAIDs, such as ibuprofen, can be used to help with the pain. Drugs such as topical lidocaine can also help. The strept throat is usually treated with antibiotics, such as penicillin or amoxicillin. If steroids are useful in acute pharyngitis, possibly in severe cases other than others, it is not clear.
About 8.5% of people have a sore throat in any 2 month period. three or four episodes in a year are not uncommon. This happened in 2007 as a result of 15 million doctor visits in the United States. Glossitis is the most common cause of sore throat. The word comes from the Greek word grasni, which means "neck" and suffix-treaty means "swelling".
