Glad to see you found out so much in regards to your condition. I had all of the same symptoms that you listed but didn't have as extensive of tests that you did. Had my surgery in August and still on a bumpy road of recovery. The only question as far as the symptoms that you listed are what type of head circulatory problems. Do you ever get numbness in you back of the ear region and pain in the forehead? I had that in addition to headaches.
