I've read all comments on this problem and realize I am in great company.
I started getting migraines about 4-5 years ago with no apparent cause. Within the last year I have been under great stress (my 13 year old son had a bleed in his brain and we almost lost him in may 2005). He still has the underlying condition and every day is full of reminders.
I have been getting these stabbing pains that last 5-10 seconds and then move on the other parts of my head. Mostly behind my ears and that also gives me ear aches and sometimes I need to pop my ears. The pains come and go, more come than go. I also get the pain in my sinuses and that make pretty well everything hurt from the shoulder blades up.
I work at a computer all day and can't shake the pain. I don't know how long I will be able to deal before I do go insane.
I only good thing is that all you people have written and it makes me feel better that i'm not the only one.
Hope to all to find relief, and when you do please let me know.
