Worse again in recent months

I have had migraines since I was 15, was "officially" diagnosed 17 years later after spending years of trips to the emergency room and losing weeks on the couch.

Was given Topamax when diagnosed with Migraine and worked well for few years, only had hormonal migraine monthly but was tolerable and treatable.

In recent months/year, am seeing change again in migraine. Having more frequently and lasting longer. This one has hung around for 5 days. Can't sleep, can't sit with eyes open, hate the light, hate the sound, hot and cold at the same time and not able to confine to one known trigger.
