The best treatment for migraine eye pain or nausea is to rest in a dark room. Make sure the light is as low as possible, and that there is little noise or only soothing sounds. Lie on your side to relieve nausea.
Take a dose of medication especially manufactured for migraine pain. Go and lie down in a quiet place in the dark and try to sleep while the medication does its work.
For the migraine, Imitrex can be prescribed. If that does not work, a steroid shot could be given. For the nausea, Promethazine should be administered.
