I woke up trying to figure out if one could make a bandage with gauze and beeswax. But the wax would have to be way too hot. So then I thought, you could mix olive oil and beeswax in a double boiler, and let that cool, and it would be a salve, you could make it like a a little softer than a chapstick. So if you are into things like that or have a friend who can do that, I would consider making a salve (if you can find comfrey salve that might be just the thing), and dab it onto the wound three times a day immediately after cleaning it off. Just some brainstorming here.
Until it heals up some, I would add water and make the food like a slurry, like milkshake consistency to make it easy and less painful.
Please keep us posted.
