<s>[INST] my mom had a hospital stay of 5 days with low sodium from a uti infection last week.she has lost all her strength in her legs.she walked 3x a week prior too this.she is at a n home getting therapy how long until her mind and legs come back she is in great health for 80 yrs old thank you. [/INST] Hi, dearI have gone through your question. I can understand your concern. She has low sodium secondary to urinary tract infection.  She should complete the course of antibiotics.  She should take saline transfusion.  In old age recovery takes some time so no need to worry.  She will recover soon. Take treatment according to your doctor's advice. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using health care magic. Wish you a very good health. </s>
