Feels like Something stuck in Throat?

3-4 weeks ago I was eating popcorn and it felt like I got a husk stuck on my left tonsil. Then 1.5 weeks ago it felt like whatever it was moved to the middle of the throat. I felt like I was chocking and went to the ER and they took an x-ray said they didn't see anything maybe allergies. I went to an ENT and he looked down my nose with a scope and said he didn't see anything and call back in 2-3 weeks if i still have the feeling. He tried to blame it on me smoking but I had quit back in Jan. and was a 1 pack a week anyways. I have tried gargling a few times a day, eat soft foods, tried hot tea, cold Popsicles. I have no post nasal drip or allergies but I am going to try allergy meds starting today. I have the sensation of something stuck all the time with no relief and it makes it hard to sleep. Do not know what I should do next? Find a different ENT? I cannot go on like this. I feel like I am gaging. I do not think it's tonsil stones either because there is no with patch on the tonsil and my breath doesn't smell.
