Re her sore back leg - were any of her injections in her rump? I don't know if there is any connection, but I have noticed several times over the last few years, especially in the Tamworths, that there seem to be limping problems in the back leg/legs a few days after an injection into the rump area. I spoke about this with the vet recently, and he thinks the needle may just have hit a nerve or blood vessel causing internal bleeding/bruising. I was in a complete panic about one of my Tamworth weaners almost unable to use her back legs a week ago, 2 days after an injection into her butt, but she is absolutely fine now. Just a possibility - Tamsaddle
