I have had migraines since I was pregnant, about 7 yrs ago. They are constant but seem to get better at night (with the right medication) and then worsen as the day/week go on. Am now taking Levetiracetam (ie Keppra) that seems to slow the onset and decrease the intensity of my migraines. But light and sound still bother me though not leading to as intense of a headache. The other migraine problems e.g. left "weakness" have not gone away but the pain is much less, thank goodness. How can I have the migraine "problems" but the pain be less. Why does the Levetiracetam work??
