question: my husband is diabetic, he has not been well lately. His feet has been very swollen, and he got celulittis on one of his legs. Today when he woke up he had a rash all over his body. He went again to the doctor and the doctor said that he believes it is from his kidney. he put him on predisone 20 mg. 2 times a day. What I want to know is this a prelude to diaylsis. thank you.
