Hi, my son 5 years old has been complaining of blocked ears for 3 weeks now. Brought him to his paeditrician and was told that this is caused by the fluid/mucus stuck in his ears. My son has nasal allergy as well. He started to complain headache these few days. Went to the dr. again yesterday, this time around i was told that there were some build up of ear wax in his ears and the headache most likely is caused by the blocked ears. He used to complain of blocked ears during or when he is in the bed, lying down position. kindly let me know what to do in order to help with his blocked ear and headache? Thanks dr.
