migraine
"Imitrex shot is a very effective drug for me. Have had migraines for decades and was introduced to imitrex after 2 years of having blinding aura then 2 days of suffering in a dark room. Imitrex shot works within minutes. No pain killer needed. Once I give myself the shot, I lay down for about an hour. Only issues are brief fatigue, nausea for a few minutes and a strange prickly sensation in the top of my head which goes away quickly."
