My mother is 81 years old and the lower parts of her legs are a deep red almost purpleish color.She now says that sometimes she doesn t have feeling in her feet .Her doctor says he is unsure what is causing this.To me I think of PAD.She is getting what looks like a rash she has little round sores about the size of a dime all over her legs all the way up to her groin area,some are open sores from itching.Please what do you think she has? She is 4 10 about a 100 lbs she has only really had problems with low sodium which is getting better also within the last 6mths she was admitted to hsp with a UTI that she was unaware of having,and it was bad..Thank You email address: YYYY@YYYY
