I was asked to go to a headache clinic through a survey I filled out online. I know that they take into consideration your insurance and any other meds that you are taken or have taken. I had to turn the offer down unfortunately because the clinic was a few states away from me. It's kind of sad though, because I have only been suffering from migraines for three years now and sometimes I feel like I just can't take it anymore. The information may have been helpful.
