My sister has had multiple leg surgeries in the last 5 years. She has been on insulin for 25 years. She weighs 93 pounds. 2 months ago she had a below the knee amputation on her left leg. She developed an infection and has had this cleaned out many times in surgery. The infection smelled and was bad so yesterday the doctor took her in to clean again and said she had atherosclerosis with gangrene. They sent her home in 2 hours alone and told her to call in a week or two to make another appointment. They are now talking about next time taking bone from right leg to put in left . She has heart problems, diabetes, cholesterol and Parkinson's badly. She is so frail. I would appreciate a doctors prognosis on this and please pray for her. Her name is nancy. Thank you ever so much!
