Your wife has unfortunately likely developed chronic daily headaches
if her condition has been afoot for at least 3 consecutive months and you are certain there are no other causes for her headaches.
For example, have they recommended cervical plains films or even CT scan
to look for evidence of degenerative arthritic disease which can often cause headaches which appear to be migraine
like but are actually radiating upward from the affected side of the spinal column through the neck and into the head? Perhaps, there is a pinched nerve
in the neck cause cervical radiculopathy
This may be seen better with an MRI
study. And there are other causes for her headaches that could be investigated.
My recommendation is that you speak to your primary about getting an appointment or referral to see a neurologist
who is also a headache specialist. She will undoubtedly benefit from such a doctor's fresh look at the problem to get her on the right track and find other potential things that could cause headaches otherwise, overlooked by her primary or others to this point.
Hope I have answered your query. Let me know if I can assist you further.
