What causes headaches?
There are many causes of headaches. When headaches persist, it is important to exclude sinister causes including encephalitis, meningitis, tumours and stroke. Other causes may include tension headache, migraine, cluster headache and cervicogenic headache.
Can headaches be treated without medications?
Migraine that is not responding to oral medication may respond to Botulinum toxin injections of the muscles of the face, head and neck.
Cervicogenic headaches arise because of abnormalities in the neck or cervical spine. Steroid injections or nerve blocks of the cervical facet joints or radiofrequency ablation of the nerve supply to the facet joints may help relieve cervicogenic headaches.
What is radiofrequency (RF) ablation?
RF ablation utilises RF energy that is generated through a machine to create heat. This heat is transmitted through a special RF needle to destroy the painful nerve branches of the cervical facet joints. This is a day surgery procedure that is performed under X-ray guidance with mild sedation.
