lately I've been rotating along my forearms, wrist, and hands in an effort to practice safer injecting and vein preservation. This means that I inevitably have to hit rolling veins, which I once felt was impossible. I've developed a technique though which allows me to almost always register. For the vein that's on the side of my wrist, that kind of winds down from my middle finger and sort of along my thumb, I push the needle in a little before or after the wrist joint. Sometimes If I just do this and am clenching my hand in a very tight way, I can hit this vein without it rolling. However, usually it will roll, so what I do is keep pushing the needle forward into my wrist (by now, the entire length of the needle is in the skin), If I push it maybe a few centimeters more, I will hit the vein, and proceed to shoot. (btw, I'm injecting at an incredibly shallow angle, the barrel of the syringe usually is only 1/4 inch above my arm/hand.
I've been doing this technique for close to a week and a half, and everything is fine so far, and it works really perfectly, In fact, I havn't missed a shot in a long time now. I was wondering though if this is a safe way to hit these kinds of veins, or if it can be damaging, as there is more stress on the injection site?
