If I'm not too late. It doesn't look good, but not too bad either. You need to place a frog in a quarantine. Clean papertowels changed daily, cover sides to minimize stress levels.
Prolapse - you did great job so far. Try again to sprinkle sugar ( you can do more of it then before, cover the whole thing). The goal here is to lower the swelling and not to get bacteria involved. You won't be able to push it back unless the swelling is under control. Try sugar first. If swelling is reduced it should go back on its own.
