Dear "Shines",
Hi. I am not a medical professional, but I notice that you say you will get an "ANGIOGRAM CT scan". I, and I think most of the donors here, got a CT scan of the kidneys that involved just injecting some dye, and we were up and around right away. If I understand it right an "ANGIOGRAM CT scan" may involve inserting a catheter into the blood vessel, and that may require more healing at the insertion point. Perhaps someone here can offer information on this.
I suggest that you play it safe and ask the St. Louis hospital to send you more detailed information and instructions on what exactly they are going to do, and if discomfort can be expected afterwards. I THINK that what you are describing is a more invasive scan procedure that most of us received. Check it out.
