Yea I did a little searching but was confused, as best I can tell there are different kinda of ultrasounds, depending if they are looking at blood flow or nerves I guess.

I'm not going to worry about it to much as the guy I'm going to see if apparently suppose to be very good. He has one of the longest running threads on here so I suppose I could ask there what patients experienced on their first visit.

And who knows about the armpit pain, TOS can apparently present a hundred different ways, and what I called my armpit thinking about would better be called the edge of my shoulder, which do to my skinny stature is basically right above my armpit lol, which upon looking more seems to be a pretty common complaint.
