Talk to Ent Specialist on Clogged Ears

Assalam o alaikum I have ear congestion that started 3 weeks ago. In first week ears were completely blocked. First ent said it is ear infection so I took antibiotic azomax for 7 days. Ears started to open a little then thick mucus started dripping in throat second doctor said ears are fine it is pharyngitis and mucus in throat is blocking the ears so I am taking klaricid for 6 days but the mucus is still present it is thick and sticky and it causes pressure and fullness of eustachian tubes please suggest proper medication medication.
