Many thanks to you both for taking the time to reply.

Russell - I have also been told the tone of the veins is controlled by the nerves that run right along side them. Sometimes the veins are bulging quite significantly and sometimes I wake up in the middle of the night (b/c of pain) and the veins are flat, but very blue. It's as if I can see every single vein in my hand...somewhat bizarre.

Zookester - thank you for the suggestions. I've seen a peripheral nerve specialist that I have confidence in --but I think an opinion from another peripheral vascular surgeon is a very good idea. I will follow-up on that. And, I am interested in learning more about Dr Ombrellaro. I"m going to send you a PM and I hope you might be willing to share some more info about your experience with him.

thanks again!
