So around 3 or 4 days ago I injected 2ml of sustanon. That was my first time using sustanon and before that i had only injected 1ml at a time. I think I forced the oil in too quickly because afterwards the injection side kind of hurt which usually doesn't happen until the next day. For the past few days I've had a very swollen area much larger than the injection site and it's very painful to touch and I can't lie down on that side. The swelling doesn't seem to have gone down much if at all since then but it isn't red and I don't have a fever or anything so I don't think it's an abscess but I'm not sure. Maybe a sterile abscess? Does it make sense that this would happen just from injecting more than I usually inject and forcing it in somewhat quickly?
