Can I get some answers/reurance?

Ice packs and Bute. The aspirin will help with the swelling as much as the ice. Bute has to come from the vet, but there are some synthetic kinds that work just was well at the feed store. Had the same thing happen to me, but the saddle was under the horse instead of on the side when he went over the fence. As far as something to keep the cut from getting infected, I love cut and heal. hardly leaves a scar, which will help you get that perfect QH head back.
