Ok, so last night I did my first injection ever last night (250mg sust, in the upper right thigh). The injection itself was completely painless and there was no bleeding at all. When I woke up today, the injection site was a little sore, but nothing too bad. It got worse as the day progressed to the point where walking became very painful. There's no discoloration in the area. I kind of felt like shit all day and had a horrible workout (this of course may have nothing to do with the injection).
Is this amount of soreness normal? Could this be an infection?
