Midge, migraines can definitely come from cervical problems. Though I had hormonal migraines off and on for years, they were getting less and less frequent as I age.
Then, about 3 months prior to my surgery, I started getting them and it increased in frequency as time went on. Surgery over, and the migraines left, except for the still occasional hormonal one.
