    Although I have never had aching teeth, in November of last year I began
    having cluster migraines. I had full blown migrains for several days in
    succession. The headaches were a little less severe each day. Then I
    would have only the migraine prodrome (light show and tunnel vision)for
    several days following the full-blown headaches. This scenerio went on for
    a couple of months. It finally dawned on me that the migranes might be
    related to my thyroid hormone levels (I had a total thyroidectomy in 1994,
    and was taking levothyroxine). Sure enough, my throid hormone levels were
    too low! After my endocrinologist increased my dose of thyroxine, I
    haven’t had a migrane since. Hope this info helps. Maybe you should get
    your TSH levels checked. Good Luck!
