I had the angiogram. It is where they of course put you into provocative positioning to see if the blood flows to the areas it should or if the tos is what is causing the compression. It did hurt as the arms were overhead but it did discover I had a 90% occlusion on the right side and 60% on the left side...no symptoms on left only on the right.

I can't say it was that bad......just holding the arms in the superman position sucked the big one for me...hell pain....but that's what I had to do to get my diagnosis pure and simple as vascular tos!

take care hope you make the best decision for your own health

love and hugs,
