What are throat ulcers?
Throat ulcers are a condition in which sores or lesions form in the back of the throat. If the affected tissues swell, they can potentially block the airway, creating a life-threatening situation.
Throat ulcers are usually caused by untreated respiratory infections or by disorders of the tonsils or adenoids. In addition, they can sometimes be caused by other respiratory disorders such as tonsillitis and pharyngitis. They can also be caused by HIV infection, Epstein-Barr virus infection, herpes simplex virus, or oral thrush (yeast infection caused by Candida albicans).
Throat ulcers may be accompanied by other symptoms of an infection of the throat including pain, enlarged lymph nodes, fever, difficulty swallowing, cough, and nasal congestion.
