Mentat is right on. You'll have to do the calcium very soon or it will be too late. So long as it's amphibian or reptile calcium WITH vita D3, it will work.

Captive frogs and toads do not get the calcium they need in their diets so we have to supplement them. It is only properly absorbed into the body with vitamin D3 through supplementation or by UVB rays from the sun. Calcium not only helps keep their bones strong but is also affects the ability of muscles to contract, including skeletal muscles used for movement and mobility and use of the jaws for eating, heart or cardiac muscles giving the heart the ability to pump/contract and also helps with impulses through the nerves or cardiac nodes within the heart, helping to maintain proper heart rhythms, and visceral or smooth muscles in the smooth muscles such as the intestines altering their ability to contract or move food through which can lead to constipation, and lack of the blood vessels ability to regulate sodium and potassium through the vessel walls, which can alter the control of fluid control in and out of the vessels and intracellular and extracellular spaces causing swelling or edema. Basically, to make it easier to understand... Low blood calcium levels can cause numbness, tingling, twitching, tremors, uncoordinated movements, seizures, paralysis, inability to move jaw or chew, weak bones and soft jaws, cardiac dysrhythmias, swelling/edema, constipation, and I'm sure I'm missing a few. Other electrolytes needed to perform these function are sodium, potassium, and magnesium in varying smaller levels. This is why it is also important to provide a multivitamin powder supplement once a week, as per instructions of the particular mvi chosen.

It sounds a lot harder than it is. You may need to use a liquid replacement for calcium if it becomes any worse. Your symptoms are advanced and will quickly lead into metabolic bone disease and if not treated soon will lead to death of your amphibian(s).

The pedialyte soaks will indeed help with loss of sodium and potassium. You will still need the calcium right away, and to start the mvi soon too.

Please also use these supplements for your toads. It is the same for them.

I can teach you more if you'd like, but this is a good start.
