My mom, 95 1/2 years old, says she is tired, not a surprise, but also that her chest is tired and her extremeties are cold. She hasn t been sleeping well the last couple nights. She does goes to areobics 2 times a week and is very strong and active. However, I m wondering if I should take her to ergent care, although I will have a fight on my hands. As I mentions she is very strong, not just physically but mentally, too.
