Hi Gunny Fitz,
Headaches suck and blow at the same time. At least putting my Topiramate doses up have cut the daily attacks.
We had a chat about Numeric Pain Scales, the differences, and the chances your Dr is referencing a different one to you here:

There are some good Scales I would take, modify and expand on to fit purpose. That way you get exactly what you want, and your Drs see a document they are familiar with.
Good luck with it.

Dave.
