Does mud fever get to a point where your horse starts limping? My mare is recently starting to limp on her leg that has it, there's not sign of other lameness in her leg. Is there also something like a tube paste tranquelizer that I could give her when I try to pull off the scabbies? I'm trying to get my mother to take her to the vet, but she won't because it's "not bad enough", but if lameness is abnormal, my uncle said he'll haul my horse for me.
