When you get the headache, try and keep a log of what you did, ate, etc right before you got it. Then you can look for similarities in what can be causing it.
Hello,
I am sorry you are having headaches. I don't know much about them and for that I apologize. I've had 3 Migraines in my life, went to ER and the medications they gave me helped tremendously.
So that said are you aware that we have a Migraine and Headache Forum that ma be more helpful in your quest. Just click on Forums on the top left side of this page and that will take you to the list of Forums.
Best of luck. And again I am sorry you are having such pain. Tuck
