You might also try a good soak in Epsom salts. I remember spraining my ankle in a church in Milwaukee on my way to communion (there was a small step from the pew to the aisle) and listening to the Miller Beer Can Banks rattle in my purse as I fell...talk about humiliating! lol Anyway, I put Tiger Balm on it and it helped too. Have you contacted any behaviorists about Duncan and his aggression?? I sure hope it all works out for you. Keep in touch and I hope you find a new place to live soon!
