I read this on sportinjections.com but I'm still a bit confused on this part of the process:
"*Aspirate the syringe - pull back slightly on the plunger - you will see one of two things. (A). You will see a couple small air bubbles that when you stop applying pressure upward on the plunger will readily go back into the muscle or (B). Droplets of blood. (A) being the obviously favorable one. If there is blood you must pull out, switch needles and start over."
Exactly where would I see the air bubbles when I stop applying pressure upward on the plunger? What am I actually doing when I aspirate? If anyone could give me more info on this process I would appreciate it.
Thanks
