30 hours ago i injected 1 gram(4cc) of sustretard with a 1 by 23 ga needle into my right glute. at the time it was not irregularly sore or anything, good aspiration, no blood. I also cleaned needle and site with alcohol. it huirt this morning but a few minutes of walking on it was ok. took some ib profun(anti-inflamatory) that made it feel better. as the day went on it got a little more sore and alittle moderate swelling on my right side of cheek. now it hurts and is swolen more, i have sust flu like a champ and feel like shit. what the fuck do i do and what did i do wrong? was the needle too short or what. ive never shot more than 3cc in my glute and that was last march. is it jsut swelling from the amount of medecine or an infection?
