My dr said the headache would get a lot worse for about a week or so, mine didn't last that long. I would give anything to be able to get them again, but because I broke out in a rash all over a few hours after the injections there was no way I could get them again. If they helped you, then it might be worth getting them again.

Also as Dr Smith asks, have you tried any anti-seizure meds for migraine prevention? I was on Topamax for years and it did wonders for me, cut down the frequency of my migraines big time!! I was on it so long that the effectiveness wore off.

The best migraine meds I ever took was Amerge. But, as always, I developed an allergy to it.
