Fo the past 3 or 4 months I have had a feeling of a lump in the Right side of my throat that bothers me when swollowing. It comes and goes. It does not hurt. I also have a burning or dry feeling in that same spot from time to time. The past month I seem to have developed more mucus than usual and I am constantly clearing my throat. Sometimes when I yawn I get a bad taste in my mouth. I also get a lot of anxiety since this began. recently My chest has been feeling uncomfortable like there is fluid or something in there. I am a nonsmoker for a few months now and i don't take any medications.
