Pharyngitis is another term for sore throat. The pharynx is the part of the throat between the tonsils and the larynx, or vocal cords. Acute inflammation and infection of the pharynx can be caused by bacteria or viruses. Chronic infections can be caused by similar mechanisms as well as other chronic irritants. The nasal mucosa may also be involved.
Causes of Pharyngitis
Acute pharyngitis is most commonly caused by bacteria or viruses. The most common forms of bacteria to produce sore throat include streptococci, gonococci, Haemophilus, pneumococci, corynebacterium or staphylococci. A number of viruses may affect the throat or the entire upper respiratory tract with infections. Constant irritation from smoking, from excessive alcohol use, from allergies and from breathing polluted air, can all lead to chronic sore throat. Fungal infections can occur, particularly in those whose immune system is compromised or those that are on various antibiotic therapy.
Signs and Symptoms of Pharyngitis
The symptoms of pharyngitis include sore throat and painful or difficult swallowing. You might complain of a tickle or lump in the throat. Frequently, pharyngitis is associated with elevated temperatures and swollen, tender lymph nodes produces lumps in the neck. At times there may be a film or membrane covering the throat or tonsils. Some cases of pharyngitis are associated with generalized aches. Chronic sore throat can occur from irritants, such as smoke, alcohol or allergies. Frequently, the mucosa of the nose may be involved, producing Rhinopharyngitis.
