Which symptom is NOT associated with an erythematous tympanic membrane?

The correct choice indicates that the symptom described is not typically associated with an erythematous tympanic membrane. An erythematous tympanic membrane refers to the eardrum appearing red or inflamed, which is a sign of potential issues such as infection or trauma.

Redness directly correlates with the definition of an erythematous tympanic membrane, as this is the primary characteristic. Additionally, potential infection is often indicated by the presence of erythema, as infections can cause inflammation that leads to redness. Pain in the ear is also commonly reported in conjunction with an inflamed tympanic membrane, as conditions like otitis media can cause discomfort.

However, a clear appearance would not be associated with an erythematous tympanic membrane since redness suggests underlying inflammation, not clarity or transparency. Thus, clarity contradicts the condition of erythema, making it the appropriate choice.
