migraine
"I had migraines for nearly 35 years after working in a building that had been "bug bombed" overnight.  About 10 years ago I realized they only came from neck pain and chiropractic did not help.  After an exceptionally bad reaction 3 years ago to Cafergot, I was prescribed Maxalt and it became my wonder medicine.  I have not had a migraine now in nearly 18 months (something in my neck has moved to relieve the pressure) but I still take Maxalt when nothing else will get rid of a bad headache after all night pain last night, it was gone in 10 minutes when I finally took it this morning.  I wish I had known about it decades ago, none of the other triptans worked for me."
