Chronic sore throat could be caused by GERD (aka gastroesaphageal reflux disease, commonly known as heartburn), seasonal allergies, immunodeficiency syndromes, or chronic viral infection. If by "sore throat" you mean that you have pain on swallowing or you feel like food gets stuck on the way to your stomach, you could have a medical problem with your esophagus.
