You never answered whether you dust your frogs food with calcium or multivitamins??? You must do this. With out calcium with Vitamin D3 you're frog can get MED(Metabolic Bone Disease) which causes their bones to be brittle or rubbery. They will have trouble with movement and closing their mouths. Lack of vitamins can cause many different problems including neurological issues that can make them loose control of their limbs, have seizures, and not be able go use their tongue to catch food.
I'm assuming that you don't provide calcium and vitamin supplements for your frog. If you can still get her to eat by force feeding you need to go out and get both a calcium supplement and multivitamin for Herps. Also dint use bottled water because most still contains chlorine. Either completely natural spring water or treated tap water. You can buy Prime or ReptiSafe de-chlorinating agents to treat the tap water. Start doing this immediately. If youbcan find liquid calcium you can place some in her bath while you soak her. Use plain Luke warm de-chlorinated water without honey.
Also try a Pedialyte soak. 10 to 1 ratio so for every 10 ounces of Luke warm de-chlornated water add 1 ounce UNFLAVORED PEDIALYTE. It must be UNFLAVORED PEDIALYTE. Soak her in this solution for 20 minutes. While she soaks you can pour some over her back as well.
I hope that these at home treatments help, but I do not want you to get your hopes up because I'm not sure what is wrong with her.
Keep us posted.
