Hi for the past 2 days it feels like something is stuck in my throat. It is not painful at all. It also seems to come & go during the day. I am currently taking Zyabn to quit smoking, which I have been on for 6 weeks. I have not had a cigaret for 5 weeks. As far as general health goes, I have the typical Zyban sysptoms, Eg: lack of sleep slight headaches, but other than that I feel fine with no other problems, just this annoying feeling in my throat. I am now paranoide I have throat cancer or something horrible. Any suggestion as to what this could be?
