Some people find accupuncture, TENs and ice on the back of the neck helpful. I've had no luck with meds and find that I often have to retreat to a dark, quiet room and stay very still.
When I asked my neurologist what would get rid of my 24/7 headache, he said, "Do you own a Smith & Wesson?"

Yes, he is such a compassionate healer.
Good Luck
