CONCLUSION
Chronic migraine headache is a disorder restricting daily living activities despite medical treatments, adversely affecting patients’ quality of living. The recently used GON block has brought a new perspective to both acute and chronic migraine treatments. The GON block has become an easily applicable, preferred method with proven efficacy and few side effects in chronic migraine patients. Besides increasing the chronic migraine patients’ quality of life, it also reduces chronic drug consumption, related side effects, and treatment costs. The GON block, the efficacy of which has been shown in numerous studies and which has an exceptionally high benefit rate, might be considered as a treatment option before migraines gain chronicity, patients are not exposed to an excessive medical burden, and increased treatment costs.
