Over the course of the last few months, much of the time, my mother simply cannot get her legs to budge. The precipitous decline is what is confusing. At times, especially in the morning, she can use her walker. At other times, it takes two people to get her from her wheelchair into the bed. She has had chronic UTIs this year. She was put on Cephelexin as a prophylactic measure but to no avail. Could there be an underlying infection that none of the antibiotics have touched over the last many months? I don't believe it is just the PD progression. It happened too quickly?! Advice, please?
