As for a blood transfusion well first off it does require a good sized needle and the veins in my elbow area of my arm are beyond shot. So are most of those in my hands, wrist, etc. So typically they must go for a back of the arm one or other deep vein. Never super pleasant.

They typically will give people benedryl or something along those lines prior to a transfusion which can make you drowsy. You do sure in the hell feel it going in. The blood is kept refrigerated so it goes into your body cold. It has a unique feeling, it may burn slightly at first (few seconds to minutes) and then it just feels sore and weird. Assuming they are not pushing it on you. A single transfusion is rarely pushed and they allow a couple hours for it to go in. Now when they want multiple units in you, then that is another story and they speed up the drip/pump machine. That can border on a dull constant pain, plus they have to check up on you every 15-30 minutes for vital signs.
