Many with migraine never have headaches or auras or any of the stereotypical symptoms. Here’s some of the other things that it can do…
"Not only is the term “migraine” misleading when it’s used to designate one specific type of headache, but even the term “headache” is inadequate to cover the full spectrum of discomfort generated by the migraine mechanism. Discomfort may be felt anywhere in or around the face or neck as well as the head. Words such as “ache” and “pain” may not even begin to capture the discomfort you feel as a result of migraine.
Instead, in or around your head you may experience pressure, fullness, tightness, heaviness, thickness, numbness or soreness, or you may have swelling, burning, buzzing, vibrating, boring, piercing, drawing, expanding, tingling, trickling, bubbling, crawling, shifting, or rushing sensations. These sensations may be aggravated by bending over, straining, sneezing, coughing or exertion, or if you shake or jar your head.
You may have feelings suggestive more of lack of clarity than discomfort, such as cloudiness, dullness, fogginess, or fuzzy-headedness. Discomfort may be excrutiating, trivial, or anything inbetween…The severe headaches conventionally labeled “migraines” occupy a relatively narrow band at the far end of the spectrum."
"Normally your vestibular system controls your balance by means of the fluid-filled semicircular canals in the inner ear. These peripheral sensors are connected by nerves to certain pathways and centers in the brain stem and elsewhere in the brain, and when vestibular function is disturbed by migraine, it may be felt as unsteadiness, loss of equilibrium (like just getting off a boat), being off-balance, veering, swaying, falling, rocking, vertigo (a spinning sensation) -or just vague, nonspecific dizziness, lightheadedness, or wooziness.
Symptoms of migraine, especially these vestibular symptoms, are sometimes trigger-specific. Just as sunlight glare or a flashbulb going off in your face may specifically provoke a classic visual aura of flashing lights, so may the vestibular stimulation of moving your head rapidly or into a certain position cause vestibular symptoms of migraine. It has long been recognized that car sickness and other motion-induced ills are commonly related to migraine and reflect the heightened vestibular sensitivity of certain individuals, courtesy of their relatively low migraine thresholds.
As with all other neurological symptoms of migraine, vestibular symptoms can be transient or persistent and can occur with or without headache or other accompanying discomfort. The site of migraine-related blood vessel constriction causing dizziness can be either in the inner ear or in the vestibular pathways and centers of the brain. The term “basilar migraine” is applied to intense episodes of migraine involving profound vertigo, imbalance, loss of consciousness and other symptoms arising from constriction of the basilar artery, which supplies the brain stem."
