Feeling as something is stuck in my throat.

hello, all.

  To begin with I have experiencing this for quite sometime now but it seems to get worse. When I wake up I feel as of that im fine but still have feeling that there is something stuck in my throat.

After I eat it gets worse, but what I do notice is that I burp a lot and the feeling of something stuck gets less. it is as there is trapped air in my throat. I have also been experiencing some  pain in my throat.

I have been to doctor and they say that my throat was all red so she prescribed antibiotics along with something for acid reflux but no luck..

I can still swallow, speak, and talk normally. and when I lay down the feeling in my throat gets twice worst.

Also, whenever I talk im starting to accidentally bite my own tongue for no reason.

is there anything that might be causing this?? I'm scheduled for another appointment but with all this happening to my throat I'm starting to be afraid...
