I Have Had A Migraine For About 10 Days With

I have had a migraine for about 10 days with little relief. At the base of my skull, I have some tenderness when touched, although I didn't experience any injuries. When I saw a doctor about the ongoing headaches, he referred to the area as something specific but because of the pain I was in (migraine), I wasn't thinking clearly. Can you tell me what this might be and what I can try to relieve it?
