Sorry Amy ,
I'm also sorry I missed this post. Poor baby.

See if you can get her to soak. Make sure you do not soak her in distilled water!(it will make her worse)
Has she been eating an pooping? wake during the day ?

Sometimes it could be from a big parasitic load? ( flagellates and lungworms )
There are many strains of micobacteria infections that can cause this.

She is definitely edematous.
It could be a renal ( kidney ) problem
Sometime frogs can develop kidney failure due to vitamin toxicity, or previous medications.

I hate to say it, but I think it's best to call the vet as soon as you can.

What medication was she treated w/ when she was ill, how long was it used?
