still have a massive headache

Well so much for my goal this week to work out every day with my trainer. I've had the worst headache all week and I have yet to shake it. There are times during the day where it is a dull pain but I just know as soon as I start moving around it will flare up to a full blown migraine. But I'm staying positive eating right and it won't be the derailment of my weight loss challenge!
