So i cant find any answers to my question, i did search but no one asked it the way i wanted it to be asked. So my rat did a 1cc shot of cyp and the day after he has a lump in the glute. Its been four days and its still there, he always keeps things sterile. There is no pain unless provoking it by touching too much, no redness, no finger indent, no fever. Also his dumb ass friend injected him and did it in about 13 seconss if that means anything. And also he alcohol swabbed the shit out of it before and burned going in he said if that also means anything. Any thoughts thanks guys!
