In addition to sore throat, acid reflux can also cause a dry cough and the feeling as though a lump is in the throat, according to WebMD. WebMD notes that lifestyle changes such as limiting coffee and alcohol and consuming a high-protein diet may help relieve symptoms.

Post-nasal drip refers to mucus from the nose that drips down and accumulates in the throat. While there is no infection present, the tissues of the throat, including the tonsils, become inflamed. This inflammation often causes throat discomfort or a feeling as though there is a lump in the throat, according to the American Academy of Otolaryngology - Head and Neck Surgery. The American Academy of Otolaryngology - Head and Neck Surgery notes that while antihistamines may provide relief from post-nasal drip, they sometimes cause post-nasal drip mucus to become even thicker and more irritating.Learn more about Cold & Flu
