Hi , I Would Like To Ask You A Question

Hi , I would like to ask you a question regarding my sister. She is 57 years old, mother of 4 works in the school district. She has always been a healthy person, no major health issues. In the past few weeks she has been experiencing problems with numbness and weakness in her arms, along with tingling. She is also starting to affect her legs which she is now noticing tingling in also. She has had tiredness. I am concerned because heart conditions are not rare in my family. ideas or recommendations?
