Experiencing h/a's progressing to migraines qd for a wk starting in early to mid-am. this doesn't fit my "normal migraine pattern." possible rationale?

Many possible reason: Check the region where you get the headache and see if it is a muscle. If so, then it is essential to find out why the muscle is responding to the point of pain. This could be an oral situation or you may have other cause/effect associations. I would recommend you check with your physician or dentist and get their professional help.
