Which of the following is NOT a symptom of inner ear barotrauma?

Inner ear barotrauma occurs when there is a difference in pressure between the internal structures of the ear and the external environment, typically experienced during diving. The symptoms associated with inner ear barotrauma primarily relate to pressure changes affecting the ear structures.

Ringing in the ear, also known as tinnitus, is commonly reported in cases of inner ear barotrauma due to damage or irritation of the auditory structures. Rapid eye movement can occur due to disturbances in the vestibular system, which is responsible for balance and spatial orientation, and is affected when the inner ear is compromised. Loss of coordination is often associated with vestibular dysfunction, which can result from barotrauma impacting the inner ear's balance system.

In contrast, the presence of bloody discharge is not a typical symptom of inner ear barotrauma. This symptom is more commonly associated with other conditions, such as external ear problems or severe trauma to the eardrum, rather than the inner ear itself. Inner ear barotrauma primarily involves pressure changes affecting hearing and balance, rather than causing bleeding.
