It's probably an ear infection. The few that I have experienced became quite painful after a while, a sharp pain like someone jabbing an icepick into my ear. For temporary relief I used to put a drop or two of Sweet Oil in the ear, kept in place with a cotton ball, and lay down on the opposite side. Be aware that infections love warm moist areas so this won't cure the infection, but takes care of the pain/discomfort till one can see a doctor for the proper treatment and/or medication *antibiotics*.
