According to the World Health Organization, as of September 2021, there have been over 226.8 million people diagnosed with coronavirus disease 2019 and over 4.6 million deaths from this disease. Out of those who have survived the coronavirus disease 2019 infection, many individuals have symptoms that linger on. We would like to describe the first report of a patient with a 5-month history of a persistent coro- navirus disease 2019 headache, which was finally successfully aborted with a single transnasal sphenopalatine ganglion block. A female in her early 50s presented to our pain clinic after suffering from a new, debilitating headache that began with the coronavirus disease 2019 illness and persisted for 5 months. Every evening the patient would experience a severe headache located deep inside/behind the left eye that would be resistant to analgesic medications. After 1 transnasal sphenopalatine ganglion block, the patient’s coronavirus disease 2019 headache was completely resolved.
