Toradol
"Quite effective for most severe refractive migraines and intense neck/face pain.  However, it can be a bit harsh on the stomach, especially if used more than once.  I self-inject at home (nurse taught me) and have had pretty good results, avoiding ER trips and the unnecessary use of strong narcotic painkillers.  Interestingly, Toradol didn't have the same efficacy when I was younger, about 15 years ago.  Now it has much more efficacy.  The drawbacks (for me) include: having to inject in the upper thigh, can only use 5x per month, and potential stomach soreness with repeated doses."
