terrible insistent migraine?

Eileen

I’ve had a migraine for a couple days. I take excedrin to relieve my migraines, but it hasn’t really helped this time around. I get migraines semi-frequently, but this one has been constantly painful. I am on my period, and they tend to come more frequently during that time, but this one feels like more of a shooting pain inside my head behind my left eye. Does anybody have advice or remedies for such a situation?
