Nowadays, many people sit at the computer and don't move enough. This results in tension in the neck, cervical spine and back. These complaints can also cause tinnitus. Another possible cause is craniomandibular dysfunction (CMD), a functional disorder in the interaction between the temporomandibular joints, chewing muscles and teeth.
Possible, albeit rare, triggers for tinnitus are a traumatic brain injury, a benign tumour of the auditory nerve (so-called acoustic neuroma), poisoning of the inner ear (e.g. by antibiotics), multiple sclerosis or Menière's disease, a rare unilateral disease of the inner ear with severe rotary vertigo.
Psychological factors
Tinnitus can also be a reaction to stress caused by overwork at work, conflicts in a relationship or other situations that trigger pressure, for example. During prolonged stress, the body releases more of the hormone cortisol. This leads to poorer blood circulation in the inner ear.
Factors of unknown origin
In some cases, we cannot recognise any clear physical or psychological causes in the patient that could have triggered the tinnitus. If this form of ringing in the ears is present, it can be compared to "phantom pain". In this case, after a limb has been amputated, the patient feels pain exactly where the leg or arm was removed. In the case of tinnitus with no recognisable cause, spontaneous activity of brain cells seems to take place when the "correct" nerve information is no longer available or is too weak.
