She seems better. Thank you all so much for your wishes and advice. (I'm sorry not to update sooner, but a good friend lost her dad and I've been with her pretty constantly since Friday.) The meds seem to be helping. My husband has been monitoring her for the side effects and she seems fine with that. She is still favoring the leg, but the quivering has completely stopped and the labored breathing is mostly gone --- sometimes a bit of a pant, but not like the other day. So we are giving the pills another few days and then we will see. Thanks again you guys.
