How to Stop Your Throat from Hurting. Sore throats can be caused by allergies, excessive talking or yelling, pollution, or respiratory infections. Just as there are numerous causes of a sore throat, there are also many remedies.
If a foreign object gets stuck in the throat, such as a small bone or even a piece of glass, it can cause irritation and itchiness. Coughing up the object or even gargling salt water may help to dislodge it. Psychological causes. A psychologically-induced cough can cause the throat to feel itchy even if there is no apparent cause for the itchiness. A person may also do this for attention. Disorders. Many disorders that affect other organs may also cause an itchy throat.
