In most cases, the symptoms of a middle ear infection (otitis media) develop quickly and resolve in a few days. This is known as acute otitis media. The main symptoms include: earache. a high temperature (fever) being sick. a lack of energy. slight hearing loss â if the middle ear becomes filled with fluid, hearing loss may be a sign of glue ear, also known as otitis media with effusion.
