I have this feeling of having something in my throat, not a lump, but feels like something in my throat that won't go away when trying to clear it. Have noticed forced swallowing trying to clear what ever is there. Does not hurt at all, but at times I feel like it almost makes me want to gag. No sore throat, fever or any other symptoms. I did have an endoscopy a few days ago to rule out any problems, but all came back negative. I was told if still occurs, a swallowing test would need to be performed. What is this and what can I do to make this go away...just a real nuisance.
