Answer:
omg.. i sooo read this article in a magazine where this girl had the same prob. u did and it ended up being a birth defect called "chiari malformation" and its where a part if the cerebellum- the area of the brain at the base of the head- extends out of the skull and put pressure on the spinal cord.. also 1 in 1,000 people have it but also there are triggers that cause those headaches like : stress, dehydration, loud music and caffine withdraw, when the blood vessels enlarge the inflammation causes the pain.. DONT PANIC PLEASE... i highly doubt that birth defect is whats wrond with you just take some OTC meds.. but if they last longer i would advise going to the doc.
Two suggestions. Go see a Dentist and if it's not associated with your jaw or teeth, go to an Eye doctor, and if that checks out see a neuro doctor. Good luck.
Get your blood pressure check, and tell you doctor, he or she can order test to rule out things that are causing your headaches.
I get them to when I get upset, or just a bad day, I even have noise in my ears. I try to ignore it, but it is hard. Make sure that you get enough water and rest.
it could be a pinched nerve!
I've had this myself...I see a chiroprator when this happens.
feel better soon please!
