Hi,
You should get and MRI done of your brain and cervicals! I am aspie and have had been having the worst headache for many years now, and I finelly convince my MD to get me one and they found that I suffer a Chiari Malformation. It's commonly found in people with asperger (that's wath I found on the web). And that's what gives me my headache. So just to by on the safe side you should get check.
Hope you feel better,
Drew
An other name for Chiari malformation is: cerebellar tonsillar ectopia
