Just thinking....if you don't have a reliable herp vet nearby contact Dr. Frye via email. Send him photos of your frog and explain any symptoms, origin of the frog and husbandry of the frog now. His email is dr.Frye.dvm@sbcglobal.net
I think the green spots are a bacterial infection which may be treated with baytril. Left alone the frog will probably die.
