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.
Acute otitis media is typically associated with fluid accumulation in the middle ear together with signs or symptoms of ear infection; a bulging eardrum usually accompanied by pain, or a perforated eardrum, often with drainage of purulent material (pus, also termed suppurative otitis media).
