ok. vein question is specific to the vessels feeding the heart tissue only. (coronary arteries). So not all arteries can be repair/linked with veins. only these ones. The donor vein IS in fact in your thigh/leg (great job). Its called the great saphenis* (spelling). And you can use the vein in a bypass because the coronary arteries get their blood supply from 2 tiny holes in the Aortic valve that blood flows through at a "constant DRIP" so there is LOW pressure in these allowing for the use of vessels with less pressure tolerability.

I have no idea why I brought those questions up lmfao. I was bored as hell! Still am. To answer your question, I think you'll be feeling might good after hittin those frosty nugs
