Pam, Thanks for letting us know...You will continue to be in my prayers as always. Man, that stinks not knowing...we've come so far in medicine that I always expect science to have the answers! I sure hope that the new medication helps. I have heard some very favorable things about the Headache Institute...perhaps worht the trip if this doesn't work? Anyway...I really hope relief from this new medication is fast and permanent. Hugs and prayers.
