I was injecting the left butt cheek...
I swabbed, inserted needle, aspirated, pulled plunger back, saw a bubble but no blood. I injected and pulled the needle out, Usually there is just a small drop of blood but this time there was a ton, enough to run down my leg and put a bunch of drops on the floor as I held the alcohol swab to the injection spot. I dunno what the hell that was all about, I assume I went through a vein putting the needle in but injected passed it. Should I be worried??
