Migraine
"I am a chronic migraine sufferer, and I didn&#039;t really notice any difference in using this than just the sumatriptan injection, though the injection worked a little faster. My migraine would disappear in about 30 minutes, but I would get a strange side effect: a tight, tense, mildly achy feeling in my neck for about 2 hours following administration. Like I said, my migraine was gone, but the discomfort in my neck was just as disruptive and annoying."
