Awesome, consider this an example of edema. I followed another thread and found that it was from a parasite. I'm assuming since he is wild got it is something he got into outside. I've been soaking him in some brita filtered water for the past 2 hours and his swelling is almost completely gone! He is looking like a normal, healthy frog. However, he is pretty ticked off that I'm making him stay in there. Anyway, for anyone who comes across this in a google search, soak your frog in some "sterile" water, bottled water or brita water. Plain tap water can be no good depending on your location. Make sure your little fella can breathe: I've got mine in a Tupperware with holes in it, I filled the water really high cause he kept climbing the walls, and he has a little cup in his container to stand on while he soaks. This seemed to work out well and he isn't struggling so much to stay afloat.
