Post Nasal Drip,Tonsil Stones,Hoarse Voice!!!

I have had a bad case of what my ENT calls chronic rhinitis after a nasty bout with the flu in 2006. My symptoms are constant slimy mucus in throat,white coated tongue,tonsil stones,hoarse voice(at times),nose blowing,watery eyes,tooth erosion. I don't know if these symptoms are rhinitis or not but some people tells me the symptoms could be silent acid reflux because I don't get heartburn with these symptoms. I have been seeing different ENT's and personal physicians off and on for the last 7 years all to no avail. All these doctors do is give me nasal sprays all to no avail and one ENT even performed an unnecessary septal perforation surgery. If anybody on this board have the above named symptoms can you give me a name for this ailment I'm suffering from and also a plan of treatment other than a bunch of ineffective nasal sprays. Thanks in advance for your help.
