Hello, thanks for using health care magic. Itchy throat is a common symptom for a variety of upper respiratory tract affections. Such affections include: Infections, allergies, gastro-esophageal reflux disease etc. - Infections are the most common causes of itchy throat which can be caused by bacterial or viral or fungal infections. Bacterial infections (strep throat, etc.) and viral infections (common cold, flu, etc.) can occur in healthy individuals, where as fungal infections usually occur in conditions of immunosuppression like AIDS, diabetes mellitus,etc. Bacterial infections require antibiotics unlike viral infections Allergies could be due to ingested food or inhaled particles and it persists longer and occurs more frequently and accompanied by other symptoms of allergy like runny nostrils and sneezing. Antihis- taminics such as chlorpheniramine are widely used Other causes of itchy throat include excessive strain on larynx during a singing or shouting encounter and gastroesophageal reflux disease in which there is a reflux of acid up to the throat.
