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.
Anxiety can cause your throat to feel tight. Unfortunately, worrying about this can cause your symptoms to become worse, leading to tightness in the chest, difficulty breathing, rapid heartbeat or sweating.
