Background and Aims Different descriptions of long COVID have already been proposed, and the most common description includes symptoms lasting for over three months after the first symptom onset. One of the most frequent symptoms identified, besides fatigue and dyspnoea, is a new daily persistent headache.1

Methods We describe a case of persistent headache associated with COVID-19, which had a poor response to pharmacological treatment. The patient scored a pain of 8 points in Visual Analog Scale (VAS). It was a widespread—affecting frontal, temporal, and occipital area—pulsating quality headache that worsened with mild physical activity.

Since Botulinum toxin type A has been used to treat chronic migraine for over a decade, we decided to try this therapeutic option after proving that the response to local anesthetics was positive.

Results She responded satisfactorily to bilateral greater occipital nerve block and infiltration of the frontal and temporal muscles with local anesthetic and corticosteroids, with an improvement during approximately 48 hours.

Two weeks later, we administered by ultrasound guidance 20 IU of botulinum toxin near the greater occipital nerve, and performed a mapping with botulinum toxin by administering it at different points: both trapezius, splenius, frontal muscles, bilateral orbicularis and bilateral temporal and parietal muscles. After seven days, the patient reported improvement of the symptoms (VAS 3) that were still present one month later.

Conclusions In conclusion, we propose that botulinum toxin can be a therapeutic option for persistent headaches associated with COVID-19. However, future research studies are required to clarify this possibility.
