still to early to tell IMO, prop is sometimes painful to begin with, and being that I have experience with it, no two shots are the same, sometimes they hurt sometimes they dont, I couldnt walk for three days from a calf injection, and this is after 4 weeks of prior injections in that same spot, looked exactly like that...it wasnt an abcess, just a shitty shot that week......so keep an eye on it, if any localized discoloration occurs, a high fever, or any spot usually would be the injection site in this case has any discharge, and a specific area becomes very painful.....now expect the injection area to be a little more sensitive that the surrounding tissue.... but use good judgement if it just unbearable to the touch type pain....see a doctor.....if not just keep an eye on it and ice helped mine alot.....good luck
