No, the hand is not an unusual injection site.  Half of my treatments go into my hand as they are the most accessible and reliable in people of advanced age. Veins start rolling and doing things that make them hard to hit just as a matter of age. I'm running out of useful and accessible veins in my arms.  We try there first and if they don't score, we default to the hand.  We had to use an ultrasound to find an accessible vein in my arm for the IV to inject the contrast for my CT Wednesday night.  Earlier in the day during my monthly IViG treatment we made two attempts to hit a vein and the hand did not work.  We had to go elsewhere higher up in the side of my right arm.  Nearby where the IV for the contrast ended up going.  I'm 73 now just for the record. And now I see that you deleted your post about injections in the hand as I was composing this.  You're a real POS, spam_dragon.
