Head Injuries
Trauma to the head or neck can affect the brain, inner ear, or auditory nerves and cause you to develop tinnitus. [9] This problem usually only develops in one ear, on the side impacted by the injury.
If you develop tinnitus after an accident or sporting injury, make sure to let your doctor know. They will then decide the best way to manage or resolve the problem. If the trauma caused a serious internal ear injury, letting your doctor know about your tinnitus may help them discover it.
Inner Ear Muscle Spasms
Less frequently, tinnitus is caused by sudden spasms in the inner ear muscles. [10] Most times the cause of these spasms is not clear. Sometimes these spasms are indicative of neurological diseases like multiple sclerosis. In addition to hearing loss, ear muscle spasms may also cause temporary hearing loss.
