My poor horse had a flu jab 6 weeks ago resulting in a huge swelling on his neck making it impossible for him to move until he had a large pain killing jab into his vein. He now has four hugely swollen legs, with the swelling progressing upwards rather than down his legs and has had a steroid jab, more pain killer and is on antibiotics. Bloods came back normal. Has anyone else had this and what happened?
