You can tell that employees in the company that manufactures and sells Excedrin don't get headaches otherwise they'd just use it for themselves, instead of selling it to others.

Due to comparable physiology you can readily assume that conditions which can usually cause headaches in humans can cause headaches in, at very least, other mammals. These mammals, being smarter than humans, avoid the rollainm by not opting to take excedrin.

Not necessarily. There are enough different kinds of headaches that it seems probable that at least some other mammals suffer from some kinds of headaches, but there are enough differences between human neurobiology and that even our closest animal relatives to suspect that some kinds of headaches (at least) may be strictly human.
Some examples.
There are spinal problems common in humans because of our upright posture that are not found in other vertebrates and spinal problems (particularly in the neck) are a cause of many headaches.
Hormonal imbalances associated with the menstrual cycle are a common cause migraine headaches. Many features of the human menstrual cycle are unusual if not unique among mammals so its possible, maybe even probable, that menstrual migraines are not found in other species.
Currently, there are no animal models that are considered acceptable for studying human headaches.
