Muscle tension?
It is pre-menstral. I have major headaches and back aches. I am almost 50 and I still forget the signs. Stress headaches that can sometimes feel like migraines a week, sometimes two weeks before your cycle, so it makes us so confused. And considering we have stress and anxiety it's hard to figure out which one is causing this headache. I am not a doctor, but this one I am almost 100% sure about. Warm baths, low lights and soothing music help me with those...unless it's a real migraine (which I do get) then coolness, and extreme quiet...LOL I hopes that helps you.
