What I'm mainly interested in is whether we're looking at a venous disease, or at something that's caused by surrounding tissue/bones. E.g. lymph nodes becoming inflamed (by EBV during adolescence...) and the inflammation affecting the jugulars would be one hypothetical reason for stenosies (which would mean it's not a venous disease even if there's collagen change in the vein resulting from the inflammation). But then the question remains, why is the azygos co-affected so often?

Both of these conditions relate to temperature change, principally cooling. I have therefore wondered if they somehow relate to circulation, ie if there is some sort of vascular link to all this.
