Thanks guys
We're home. There's not terribly too much to say for sure yet, waiting for blood work results, really.
She's been put on Gabapentin, to try and help with her falling. It's commonly for relieving neuropathic pain, and is an anti-convulsant. We're hoping it'll help her back communicate with her brain better, basically, and stop her legs from giving out.
She's lost 2.8lbs, which she really didn't have to lose to begin with... *sigh*
Along with her back being sore, her neck appears to be sore as well...
Really can't say anything definitive without getting blood tests back.
