In short

The internal jugular veins carry blood from the brain and head back towards the heart.
In some people a vein is narrowed high in the neck, often between the styloid process and the first neck vertebra (C1).
Whether a narrowing explains someone’s symptoms needs careful assessment by a specialist.

Who this site is for

Mostly people who have been living with symptoms for a long time, and their families.

You have symptoms such as brain fog, tinnitus or head pressure, and a scan has mentioned narrowing of a jugular vein.
You have been told you may have Eagle syndrome or an elongated styloid process, and you want to understand the options.
You have already had imaging or surgery elsewhere and would like a further specialist opinion.

What IJV compression is

The internal jugular veins run down each side of the neck. They are one of the main routes for blood leaving the brain.

High in the neck, each vein passes close to two bony structures. One is the styloid process, a thin spike of bone below the ear. The other is the side of the first neck vertebra, called C1. If the space between them is tight, the vein can be squeezed.

Narrowing can also come from muscles or other tissue. It is sometimes seen on scans of people who have no symptoms at all, which is why an experienced specialist needs to interpret it.
