New Monthly Migranes

[misshav]

My issue is the next. I know my family is sensitive to light. My grandfather even got his wedding pic with sunglasses on. I used to live in Mexico for 28 years, though it is Mexico, I lived in a place where it rains 7 months out of the year. Even when it is sunny, most of the times there are clouds in the sky, so it´s not as sunny. When it´s clear I use sunglasses, but my light sensitivity is worse with white light, like a bright cloudy day, I really can´t see. I have been able to see directly to the sun, and see the light rings around it, no problem. But the light of a cloudy day, geese I am blind. Anyways, I had always been healthy. Eventual cold, no big deal. The problem started when I moved to California. Hardly rains, 95% of the time there are no clouds in the sky, just Bright Sunny Days. I can´t be outside for more than 5 hours without coming back home and getting a horrible unbearable headache. I notice they are worse some days before I get my period. And the headache is worse if I lay down, rather than if I am standing up. I feel like more pressure in my forehead if I lay down than if I am standing. Back in Mexico I had like 3 or 4 headaches in my whole life, caused by stress at work, but here right now I am not stressed by anything, and they are so bad I can barely think straight. I can handle pain, Funny I laugh with pain instead of crying. Both times I fractured my ancles people didn´t even believe me cause of this. But this headaches are so bad that not even pills work. The only thing that has worked so far, is going to bed covering my face and limiting the light in the room to none. This makes me sleep over 12 hours to feel better.
The pain is mainly on my forehead  from where my eye starts on the side to the other side. Sometimes it´s to the point of wanting me to vomit. I get annoyed easily with white bright lights. Usually my PC, laptop and TV are to the lowest brightness possible for the same reason. I have astigmatism in one of my eyes. I know I have a sensitive sight, sometimes I see things others can´t see.
My question is: Could my head aches come from a different sea level, due diff atmospheric pressure? (ears always pop up like on airplanes when coming into town.
Could it be because it is brighter here than back home? (they just started by the time I got to California)
When the senses in your body are very sensitive to everything that is going on around you, could this cause the eyes (being a sense) to be more sensitive to even brighter light?
I have a history in family about this. All my relatives have to use sun glasses, even our eyelashes are longer than the usual cause they fracture the light coming into our eyes.

Thank you to anyone that is able to answer this.
I discarded the menstruation migranes because even if I have it before my period, I have had my period for 15 years by now, and only since I moved of home I started having them.
I don´t have a history of migranes. I worked at an airline for almost 6 years solving problems, my few bad headaches were always followed by a very big problem to solve which would take more than a day, so that´s mainly my history in headaches.
I do have sinus problems, but they never caused me something such as this, other than letting me know when it was going to rain or be colder. It all changed when I moved to CA.  Help

Hi,
Aside from the altitude, there are many possible triggers with respect to the environment. The stress of  changing your location or work may indeed have effects on your menstruation. Aside from hormonal, stress, weight loss, thyroid problems and too much exercise has been implicated with delays or irregular menstruation. It would help if you can identify the possible triggers for your headache. The headache tracker here in Medhelp may help you. Complementary and alternative medicine such as biofeedback therapy and other relaxation techniques have also been effective. When you work in your computer, micro breaks or 20 minute breaks to relax and blink your eyes can help. Take care always.

Thank you for your answer. I already went to an ophtanmologist. Though I do need glasses cause my eyes get tired after a while and I spend too much time on the computer, He said my eyes look fine. But now that you mention altitude, I really don´t know at what sea level I am here than what I was at home, and it does feel like pressure headaches cause when I stand up and when I lay on the bed, this are different levels and it gets worse the lower I am. It must be something in the change because as soon as I moved to California they started right before my period. Even my period changed, now instead of every 30 days it´s every 45. And instead of lasting 5 days which was forever before, now it only lasts 3. Weird how Altitude can mess around with your body that way. Thank you for your answer though, it gives me a new perspective, I am glad I am only going to be living here for 3 years, and not the rest of my life geese.
Have a great weekend.
