Yes I have vascular and neurogenic. My primary compression is arterial. My subclavian artery and vein are both compressed. when I bend over and come up I get really dizzy and lightheaded. When I lay flat on back it swells up and it's hurts. I just met dr Donahue in Boston and he said that vein bulging out had nothing to do with my TOS. My PCD referred me to a cardiologist and I'm seeing Dr. Lum at JH next month. I will let you know what he says about it.
