Why Equine Headshaking SUCKS

As a bodyworker and bit fitter, equine headshaking syndrome is one of the most heartbreaking conditions I encounter. Not just because of the symptoms themselves, but because of how helpless it can make everyone feel involved.

I have personally had two client horses euthanized because of headshaking syndrome. Those cases stayed with me. For years and years now.

Watching a horse spiral into that level of neurological distress is something that is hard to explain unless you have seen it firsthand. These horses are often deeply uncomfortable. Some become terrified of sensations they cannot escape. Wind hurts. Sunlight hurts. Movement hurts. Pressure hurts. Their own nervous system begins reacting to normal stimuli as if it is under attack.

Research has suggested that many horses with headshaking syndrome may have trigeminal nerve hypersensitivity, where the facial nerve becomes abnormally reactive and fires at lower thresholds than normal. In humans, trigeminal neuralgia has historically even been referred to as “the suicide disease” because of the severity of the pain associated with the trigeminal nerve. The condition was historically described in France as tic douloureux, meaning “painful tic,” due to the violent facial reactions and extreme pain patients experienced.

And honestly, after seeing severe headshaking cases in horses firsthand, that comparison is hard to ignore.

These horses can reach a point where they seem trapped inside a body and nervous system that no longer feels safe to exist in.

One of the hardest parts is that we still do not have enough answers.

Even with growing research around trigeminal nerve involvement, there are still enormous gaps in understanding why it happens, why some horses respond to treatment while others do not, and how to create more effective long-term clinical treatment plans.

After losing two client horses to this condition, I found myself diving deeper and deeper into the research because I could not accept how little support truly exists for these horses and their owners. So much of current management still feels like trial and error. Owners are left desperately cycling through medications, supplements, tack changes, environmental management, injections, bodywork, feed changes, nose nets, and specialist referrals hoping something finally gives their horse relief.

Sometimes things help. Sometimes they do not.

From my perspective as both a bodyworker and bit fitter, I also think there needs to be far more emphasis on how tack and physical compensation patterns can worsen these horses’ discomfort. If a horse is already dealing with facial nerve pain or hypersensitivity, poorly fitted bridles and bits can absolutely exacerbate the issue.

Pressure across the poll matters. Pressure over the TMJ matters. Tongue pressure matters. Bit instability matters. Tight nosebands matter. Compression over sensitive facial structures matters.

A horse with headshaking syndrome often cannot tolerate the same pressures another horse may quietly accept.

This is why proper bit and bridle fitting becomes so incredibly important in these cases. Not because tack fitting alone will “cure” headshaking syndrome, but because the last thing these horses need is additional mechanical irritation layered onto an already reactive nervous system.

From the bodywork side, I also commonly see these horses develop full-body compensation patterns from chronic pain and nervous system stress. Tight polls. Restricted jaws. Neck guarding. Thoracic sling tension. Bracing through the topline. Shallow breathing patterns. The body starts adapting around pain and anticipation of pain.

But despite all of this, there is another truth that needs to be spoken about more honestly:

Some of these horses cannot be saved.

That is devastating to say, but after witnessing two horses lose their lives to this condition, I think it is important to acknowledge the severity headshaking syndrome can reach. There are cases where quality of life deteriorates despite dedicated owners doing absolutely everything they can.

And sometimes the kindest thing we can do is let them go.

That is not failure. That is compassion.

I truly believe there needs to be far more research directed toward real clinical application for equine headshaking syndrome. Not just identifying possible mechanisms, but developing accessible and effective treatments that veterinarians, researchers, bodyworkers, and tack professionals can actually implement together with better success rates.

Because right now, too many people are left watching horses suffer while desperately searching for answers that do not fully exist yet.

And these horses deserve better than that.
