Hello... Last night I gave a doe a IM injection around the shoulder (Bio-mycin, 5cc). I think this is actually my first IM, although I've done lots of SQ's. She wasn't putting weight on that foot this morning. I've heard that an improperly given IM shot can cause a goat to be crippled. I assume this is just temporary? Should I be doing anything for her? How long will it last? thanks, and sorry if these are newbie questions!
