Tinnitus is commonly described as a ringing within the ears, but it can sound like roaring, clicking, hissing, or buzzing. It can be described also as a whooshing sensation, synchronous or not with your heartbeat.

It is a symptom that shows something is wrong in the auditory system and generally, the causes of tinnitus are otologic causes, neurologic causes, temporomandibular joint, masticatory muscle disorders and poor venous outflow from the brain into the neck. It is sometimes possible to treat tinnitus; investigations should be performed with dedicated imaging mainly in case of unilateral symptoms (tinnitus in only one ear).
