So I am not a regular IV user but I still have a hell of a time finding good veins. I am pretty sure I am hitting the one in the crook of my arm but not positive if I am hitting or missing. There is no pain at injection site and after I pulled the needle out it bleed a little bit and there was some blood in the syringe to. Does that mean that I hit? I have missed before and it is usually a little sore and get a bit swollen. The main problem is that this dope is fairly dark and it?s hard to see the blood when I pull back. I really don?t wanna waste this dope skin popping, not to mention the possibility of an abscess, so just want to figure out if when there is blood in the rig after the shot if that most likely means I was in a vein? Also no bump or pain at the injection site, is probably a good sign I would assume?
