You should'nt be hitting a vein when injecting. You want the T to go into the muscle, not into the blood stream. I'm
sure the nurse knows what she is doing, so don't worry about a little bleeding. And, if you start injecting yourself,
the nurse will show you how to check to be sure you are not hitting a vein before you inject the T. Also, if you learn to relax your muscle before the injection, you won't get the muscle soreness or bruising.
