If you move the needle 1mm or even less after you have aspirated it can still hit a vein, pulling back can rupture nearby veins and cause you to think you were in one. I notice i aspirate, but then when injecting the muscle sinks in a little more under the injecting pressure. With one hand it's just a pain in the ass.
If you've got 2 hands and think you can aspirate exactly to the micro meter on the spot where the fluid is going once you start to inject then i guess aspirating makes it almost impossible to put the substance into your vein.
If you are doing a bodypart where you can only reach with one hand, then i usually just push a micro amount of the substance in, then wait 60-90 secs, then another micro amount in wait another 60 secs. No coughing, chest pains or feeling faint then slowly empty the rest in.
I have hit a vein 2 times, once after aspirating and once with the waiting method. I used to get a lot of muscular pain after aspirating, due to movement of the needle and maybe the pressure of sucking out muscular fluids. Now i never even feel it the next day.
disclaimer --- don't blame me if you try this and your heart explodes, or lungs collapse. Just saying what i do now, after a long time of sore and annoying shots after aspirating. If you're skipping aspirating because of saving time then this is not for you. This takes a lot more time, but just helps if you're getting a lot of muscle pain from needle movement.
