Equine

Horse Headshaking Trigeminal Neuralgia Welfare

Equine headshaking associated with trigeminal neuralgia causes severe chronic pain and is a major welfare concern.

Key Facts

Photic headshaking is triggered by bright light activating the trigeminal nerve pathway
Affected horses show violent head-throwing, rubbing, and nasal discharge during attacks
The condition causes intense facial pain comparable to trigeminal neuralgia in humans
Nose nets, dark environments, and medical management reduce severity for some horses

Welfare Considerations

Headshaking causes episodes of severe acute facial pain that are deeply distressing for affected horses. The condition has ended many horses' ridden careers. Effective pain management and environmental modification are welfare priorities. Euthanasia may be necessary in severe, refractory cases.

What You Can Do

Seek specialist veterinary assessment for horses showing headshaking symptoms
Support headshaking research and owner support networks
Work with your vet on a pain management plan for affected horses
