I have a strong preference towards IVing into the vein inside the crook of my right elbow towards the outside of my arm. There's one vein there that i never miss, and is very easy for me to hit. However, i know i cannot hit this vein every time. I would like to know if anyone knows the risks of hitting the same vein over and over, day in and day out. Now, besides for the obvious scaring, what are the major risks with doing so??
