Got a 2 week old calf from a guy last night. On a rear hip the skin is all puffed up and feels like air under the skin. He had given the calf a few shots of LA 200 and thought he had given it 2 shots in that same rear hip. He said he stuck a needle in it and got just air out and it went down some. It is still puffed up and calf seems to act like that leg is sore. Never seen anything like this, any ideas?
