First........Throw those damned cigarettes away while you are still young and your body can begin to repair the damage they have caused. That was the hardest thing I ever did in my life......Been 16 years this past january. The place you feel in your neck, could very well be a sort of polyp. My uncle smokes one right after the other and over the years has had several of these removed. He also had canker sores in his mouth. Not sure if this is related to smoking, but being a mom.....I just felt that need to try to say something.....I do hope your physican clears this up. I also hope you take over your life and control the cigarettes...Not allow them to control you.....Good luck young man! 8)
