Description
Catarina Vasconcelos Fonseca and Alexandre Camões-Barbosa weigh botulinum toxin for neck-driven headaches in a 2026 review. Cervicogenic headache starts in the neck's joints and muscles and is felt in the head, and toxin injections promise relief by relaxing muscle and dulling pain signals. Only five studies qualified: four randomised trials and one prospective series, each doing things differently.
Diagnosis rules, toxin brands, injection maps, target muscles, and outcome measures all varied, with trapezius and splenius capitis injected most. Most studies reported less intense or less frequent headaches, especially with trigger-point guidance and in stubborn chronic cases. Yet the single high-quality placebo trial found no real advantage. No serious harms appeared anywhere. The pair calls the picture inconclusive and asks for standard diagnosis and protocols before clinics can know whether the toxin earns its place.
