aVNS treatment can help with the following pain indications:


  • Chronic back pain
  • Chronic cervical syndrome
  • Migraines
  • Acute post-operative pain.

Your doctor will attach three small needle electrodes in the pinna of your ear. A small battery-powered stimulator is then attached to your neck behind the ear, which uses the electrodes to stimulate the vagus nerve in a special rhythm.

The perception of the stimulation can vary, but you should feel a clear but comfortable sensation. You will feel a light throbbing or pulling sensation, though the intensity can vary heavily for different people.

The device usually stays on your ear for 7 days. However, it does not interfere with everyday activities. The treatment can be repeated over several weeks (e.g. 6–8 weeks) on the advice of your doctor, in which case it will be alternated between your left and right ear.

The most common side effects include:


  • Skin irritation on the ear/neck
  • Pain at the puncture site
  • Dizziness
  • Nausea
  • Headache


You can also ask your doctor about potential side effects.

You should not do aVNS if any of the following applies to you:


  • Pregnancy
  • Haemophilia
  • Infection, eczema or psoriasis in the application region
  • Malignant diseases in an active stage
  • Mental and/or physical impairments that prevent the application of the treatment
  • Active implanted devices, e.g. a pacemaker
  • Over-sensitivity of the vagus nerve


Ask your doctor if aVNS treatment is right for you.

Your doctor will inform you about the possibility of aVNS treatment.
