Just like people, horses may experience headaches of varying severity. If the pain is mild it can be easily overlooked. The condition can be intermittent or constant, and to make things even more difficult, the personality of a horse can greatly influence how clearly he expresses discomfort.
How do I know if my horse has a headache?
There often are no objective signs a clinician can observe. Therein lies the problem: A horse can't verbally tell us if his head hurts. However, horses can experience very serious head maladies and show little or no outward evidence of discomfort until the lesions start interfering with bodily functions.
Do animals suffer from headaches?
The same applies to many of our companion animals; their headaches are still among the health conditions that have eluded science. But common sense suggests that any creature with a head and pain perception also has the basic capacity to suffer from headaches.
