A couple times after I've finished injecting my substance I've noticed speckles of blood in my syringe! I aspirate the needle and get nice clear bubbles, so I don't think I injected into a vein. I was just wondering what causes this?
I am thinking that when I withdraw the needle it creates a suction and when it passes through a vein sucks up some of the blood.
Also is it possible to aspirate clear bubbles, but still inject some of the substance into the vein, by not keeping the needle still?
Thanks alot for any input, I'm just wondering I've had this happen a couple of times, but no problems arise from it. Was just wondering what causes it. Thanks
