Migraine
"I have suffered with migraines for over 40 years.  I have even gone so far as having my ovaries removed to help with them.  Although it helped I am still on daily medication and I still have approximately 6 migraines a month.  I take zomig nasal spray when I get these annoyances. I classify them as annoyances because once I use the nasal spray the migraine will be 90-95% better in 15 minutes and completely gone in an hour.  The only side effects I have had is my skin becomes very sensitive...almost as if I have bruises all over my body just under my skin, I am also tired.  A 30-45 minute nap cures the tiredness."
