Throat,tongue,palate

Two months ago my left side of throat, palate started burning with pain. This pain effected my ear and left side neck which is still present. I took emflox 500 mg under ENT prof. recommendation (14 days). He said its throat infection. My burning and pain subsides to more than 70%. But I still feel burning on my left side of tongue, pain in palate (left side) and uncomfortable with throat. Sometimes it shifted to right throat as well. I do not have any fever, vomitings, swallowing, coughing problem. When i turn my neck on right side I feel pain (muscular type) inside my left ear till the left side of the neck. I am a patient of sinus and post nasal drop which remains almost all the time. Thanks.
