Talk to Ent Specialist on Clogged Ears

Assalam o alaikum I have clogged ears for 3 weeks. In first week they were completely blocked ent said it is ear infection so I took antibiotic azomax for 7 days then thick mucus started dripping in my throat second doctor said ears are fine and it is pharyngitis and the mucus is blocking the ears so I am taking klaricid for 6 days but the mucus is still blocking my ears it is thick and sticky and earlier it was in throat now I feel it below nasopharyngeal region. Please recommend proper medication and proper diagnosis.
