I have been a light smoker for past 5 years-3-5 cigarettes a day. Recently i suffered from sore throat that occurred on the left side of the throat with year pain. I went to an ENT surgeon who prescribed a course of antibiotics and anti histamines along with anti acid medication . However on stopping the medication , i feel the ear pain and throat pain have returned. I am really tensed. I am also having difficulty swallowing my own saliva and food. What should i do. What chances are there that this is throat cancer? Plus i would like to mention that earlier too i had sore throats in past 6 months. The pain emanates from the base of the adams apple.
