It sounds normal, bro. If there's no pus and no pain, you're probably just sketching out. It's probably just darker than you expect. If it was infected you wouldn't be pulling out syringes of blood so nonchalantly, it'd be very painful.
I've had sterile abscesses and maybe it's just me, but I'd have a hard time stabbing it and stabbing it. It'd probably end up CAUSING a bacterial infection to be honest. Keep an eye on it and get lots of rest, bro. Hopefully nothing more than a scare.
