about 4 weeks ago my throat, about 1 cm above my left collarbone was little sore in one spot, not like sore throat. That pain kind of went away but now it feels like something is stuck like a mini lump. If I burp then it goes away for a while, if i suck on something salty then it goes away for a while. Drinking water also helps. Smoking definately makes it come back but now it is becoming more constant. It makes me anxious. It is not sore anymore at all, not making me cough either but it just feels like something is stuck on left side of my esophagus??? I will greatly appreciate help. another thing, this started mainly after i started chewing my nicotine gum as i am trying to quit smoking.
