Always feel need to clear throat

[tylers1027]

Hi everyone - For probably the past year I have had a constant need to clear my throat and feel the need to cough, although nothing ever clears out.  I feel as if there's something in my throat and always needing to cough and clear my throat.  When I talk, it feels like there's something in my throat that I need to cough up, and I'm always doing small coughs when eating as well.  

I quit smoking 3 months ago thinking that would help; but I really feel the same.  I went to the ENT doctor finally and they did a head X-ray.  He said I had a bad sinus infection and prescribed anti-biotics, nasal steroids and a few other meds but they really didn't seem to help at all.  

Has anyone else had anything similar to this? It's been going on so long; I'm not sure what to try!
