External stimuli
Inflammation of the throat and pharynx can also be caused by overstraining the voice or by irritation of the respiratory tract, which can be triggered by smoking, dry air, dust or chemicals.
Allergies
If there is no other trigger for neck scratching or sore throat, it is conceivable that an allergy is present and an allergy test by an ENT specialist can be informative and help to prevent future symptoms.
