I'm sorry that she's in such a condition. Can you get her in the sun today ? Have you gotten more water in to her ? Lowering the temp. won't really speed anything up....some people used to say to put them in the freezer, but that's very cruel . You might as well continue to try to help her, at least you'll have done everything you can. Tremors are more neurological , probably from low calcium, and not really painful. If you can get her blood calcium levels up it might help so try to get her in the sun. If you could get a Reptisun 10.0 tube bulb it might help.
