Okay, so I had a friend give Morgan her vaccine on Thursday. Well today I am out with her and I notice that she has a lump where the vaccine was given. It does not stick out very far but is large in diameter (about the size of your palm). I can't tell if it is warm cus her whole body is warm cus it is really sunny. I was touching it and she didn't seem to mind till I pushed hard on it. I am a little worried that it could be an abesess or something. My friend has given shots before and knows how to do it that is why I had her do it. So what is your experience with this? She hasn't had this exact brand of shot before, so I don't know if she could just be having a reaction to it. She has gotten small bumps where she has had shots before but they were pretty small. She seems fine and it eating, drinking, moving around and can bend her neck both ways pretty good. Today was finally Rodeos last day of antibiotics for her absessed tooth, so I am a little bummed. I just don't know what to do. Is there any way I can tell if it absessing and what can be done if it is. I am thinking of keeping an eye on it for tonight and tomorrow and then Monday morning if it looks worse then I will call the vet out. Has anyones horses ever absessed at the injection site? What happened, how was it treated and what did you do? Thanks.
