Hello and welcome,
I'm sorry to hear about your daughter. I was very young when my first migraines started.
My doctor put me onto something that works well, two Tylenol 3s and two Toradol or if you don't have prescription medications, two Robaxacet and two Aleve and one Dramamine or two Tylenol Extra Strenght, two Aleve, and one Dramamine. The concept is that two pain relievers, with two anti inflammatories with something to help you sleep work together to relax you enough to fix the headache. These work well for me.
Is there any change she's suffering from rebound headaches?
