Thanks so much for your very helpful reply. It is possible Sam fell or injured her leg, back or neck.
Sometimes we see leg weakness with a disc or vertebra injury.
Since she IS still eating and drinking, she has a good chance to heal up if she stays indoors for a couple of days.
Apply cold compresses (not ice) to her back and neck. 5 minutes on and 15 off for an hour. Then switch to warm compresses some duration. Do another hour with the one that gives her the most relief.
Give her some milk to drink in case her potassium is low.
Drain the water from a can of tuna into a bowl. Offer it to her to replace her electrolytes.
If she stops eating, her leg swells or she cannot walk she should be seen.
Please let me know how Sam is doing.
