The throat becomes sore and scratchy. This is often the first sign of an infection. A variety of bacterial or virus infections can cause sore throat. Other irritants include smoke, dust, fumes, very hot foods or drinks, abrasions, tooth and gum infections, loud talking, or chronic coughing.
Smoking is a major cause of sore throats.
Bacteria on toothbrushes can cause sore throats. Buy a new toothbrush or boil the old one at least once a month. Sometimes a sore throat can lead to chronic fatigue syndrome, gingivitis, epiglottitis, diphtheria, laryngeal cancer, or an abscess around the tonsils. A continual throat tickle could be an indication of a food allergy. Coat the throat with raw honey mixed with lemon juice.
