Yikes! Sounds like it's time to see a vet! In the mean time, you should quarantine your little frog in a hospital tank with clean dechlorinated water soaked paper towels, small very clean dish with dechlorinated water, and maybe treat with neosporin WITHOUT PAIn RELIEVER, as the pain reliever will euthanize your frog.
Others here have a lot more experience than I, so hopefully someone will chime in.
Also, here's a link to frog emergency first-aid:

By the way, how in the world did your frog get bit by a bearded dragon in the first place? I hope they're not housed together!
