All right. Thanks for the advice. That's the strange thing! I can feel it there; have been able to for a little bit. I'll try to get things nice and toasty in the enclosure, keep soaking, and try out the massage.
Also make sure the water is no deeper than up to your frogs chin. It needs to be atleast below the chin. The water should cover the frogs vent. You must be very gentle when massaging as their internal organs can be damaged easily.
