Hello and welcome to FF Ashley! I'm sorry your toad is not well; went ahead and merged your two threads to avoid confusion. Toad definitely needs a visit to a herp vet. Maybe you can get better locations than previous search using one of these links: Arav; or Herp Vet Connection.
If none of those work for you; please contact Dr. Frye at: Milan Area Animal Hospital, David M. Frye, DVM, Veterinary services in Milan, MI, Home page. He is the veterinary Matthew mentioned and will take email consults and sell you any needed meds.
Last choice is to medicate yourself and would only do that if none of the above work. Be aware that even if you can stop infection; the toad might loose it's eyesight. Although Melafix is a good natural based medication; think a stronger and faster acting antibiotic is required. If you can find Maracyn Plus locally; it's a very effective against both gram + and - bacteria. You can pre-mix around 1 gallon (keep mixed solution in the dark) according to bottle directions with 80F dechlorinated tap water. Use solution for toads bath (chin depth water) morning and night for 20 minutes, to fill his water dish, and to soak the unprinted paper towels used for substrate. While toad is in bath, you can use an eye dropper to gently drip solution over toad's back and eyes. Again; myself rather have you contact a veterinary; but including this treatment here as a last choice scenario. Good luck and please keep us updated.
