The frequency, intensity and duration of migraine attacks are variable.
Over time, most people with Migraine have many different types of attacks.Migraines' secondary characteristics are inconsistent, like fully reversible visual symptoms ( flickering lights, spots, lines, loss of vision). You were having blindness, but now you are experiencing spots.
Patients who primarily suffer from migraine with aura may also have attacks of migraine without aura.
Less commonly, the aura may occur without a subsequent headache or the headache may be non-migrainous in type.
A migraine can cause irritation of the trigeminal or fifth cranial nerve (with branches in the forehead, cheeks and jaw). This may produce pain at the lower-end branches of the nerve, in or near the sinus cavity.
There is a link between migraine and cluster headache.
Did you have teary eyes and stuffed nose at the moment of headache attack?
