A red, bulging tympanic membrane points to acute otitis media, while purulent drainage and pain with palpation are hallmarks of otitis externa. Cerumen impaction is typically painless unless complicated by infection.
Do not attempt removal if the tympanic membrane is not intact or visualized. Always assess for contraindications like tympanostomy tubes before initiating ear irrigation.
