First of all, if you have an abortive, you should keep it with you at all times, not just keep it at home. After all, if you start to get a migraine while you are away from home, like at the mall or the grocery store, that's when you need to take it. At the very first sign of a migraine, that's when an abortive works best.
Abortives should not be used more that once or twice a week. If you take more than that, you end up giving yourself "rebound" headaches. You can also give yourself rebound headaches by taking OTC painkillers more than once or twice a week. If you find yourself needing medical help more than this, you should definitely talk to your doctor about getting on a preventative, to prevent the need for the abortive, or OTC pain medication.
If the Toradol doesn't work, don't take it. Talk to your doctor about something stronger for "breakthrough" pain. A trip to the ER for serious migraines shouldn't have any stigma attached to them, especially if you have followed your doctor's instructions. Occasionally, you might wake up with a migraine. In that case, going to the ER is your only option. However, you have to be careful with how often you go to the ER, because if you go too frequently, you may be labeled a "drug seeker" and not treated. I've had a couple of ER doctors refuse me treatment because of the frequency of my migraines. That's the absolute worst. You are incredible pain, you've waited heaven knows how long to see the doctor, and they treat you like a crack or heroin addict.
Many doctors don't think narcotics should be used for migraine pain. That makes it really difficult on those migrainuers who don't respond to other medications.
Good luck and let us know how you are doing.
