Pain from 1st time Sust

[Paddy_Irish]

Using Sust at the mo, had a shot (1 amp 250) in my ass on Friday afternoon about 4 hours prior to gym (shoulders and tricep work out).
Went to steam room after gym.

The same side of my ass is now killing me, as if someone is stabbing me when i sit down. (I always use new needles, syringes, swabs etc)

The area seems swollen compare to the other side.

Is this sust or could it be an infection?

It's normal, sust can sting a bit and cause PIP, as long it was real and you followed inj protocol you'll be fine in a couple of days.

I never had problems, guess i got lucky
