It turns out I didn't have stenosis but one jugular had a valve that was upside down, the other jugular had a membrane across it.
Both problems were congenital and have been cleared using balloons rather than stents. My Azygous vein was O.K.
Already my voice is clear and strong, last night there were none of the sleep interrupting spasms and my bladder has stopped going into spasm.
Despite having little sleep my mind is much clearer and faster.
All the team in Poland were very nice and professional too. I cannot fault them.
I will post any more improvements as they occur.
Anyone going soon, there's no need to be apprehensive, this is the best thing that has ever happened to me!
