I got back the report from my MRI and the doctor said that the artery on the right side (same side as my CHs) does not go up into my head in a normal straight line. Instead it winds back and forth like old man river. I have an appointment Friday with the nuerologist to ask him about it but was just wondering if any other sufferers here had similiar findings.
Also...have had all the symptoms of a major attack for the last two weeks...ganglion lump, pain at base of skull and small pings under and around the right eye, but have avoided the demon so far. Wish me luck...

It's fairly common for veins to not always take the normal "book" route but less common for arteries to wander around a bit. However I've no idea how that might impact CHs or it may be coincidence.
