Ok, lets see if I can attach these right! I am pretty sure I have two images attached. One is instructions, one is the diary. They didn't scan in high quality but you can still see what they say.
I have a full patient handout on headaches from Medlink. I don't think it would be legal for me to scan and share it, but doctors have full access. Ask your Neurologist to give you the "Headache Patient Handout" from Medlink. Almost every Neurologist should have it as that's where the Guidelines and such are pulled from. It has 11 pages that describe in full detail every type of headache, treatment and symptoms/causes.
Hope that helps some.
