My father is 85 and his legs and feet have been swelling for a year or so, but swelling went down at night after sleeping. Recently, his swelling has become worse and often does not go down after a night s sleep. He has indicated that he has congestive heart failure and his breathing is very labored. Over the weekend, he told me that he noticed that his toes on one foot were turning black. His dr. has put him on Lasix, but he is reluctant to take it for going to the bathroom all the time, and he said that is rarely does much to reduce the swelling. He does sit with his legs up most of the time, and takes more rests with his legs up. Can you offer any more suggestions to him, and is the blackening of the toes related to the CHF, or just the circulation getting worse to his feet? Thank you.
