After a full day of tests, the doctors couldn't find the cause for Dodie's right hand and arm's lack of mobility and numbness. We met with two doctors late today, and they both gave her a clean bill of health. Her liver enzymes have come down to an almost normal level.
In short, they do not have a clue, so they told us that she could come home. We arrived back at the house about an hour ago, and she has settled in, and seems relatively comfortable.
We may never know what caused the problem. Hopefully, her arm will continue to improve.
On a positive note, the two cats and the dog were elated to have her home. So was I.
