I will try my best to answer your query There are some simple things you need to do to make sure that the amputation is not pushed up. The question has put up in Diabetes section, so i am assuming he is a diabetic. I would therefore suggest a very very good control of sugars. The control of sugars, in this case may be best on insulin. Some of the insulin administered daily can be given at the wound site. This will keep the sugars controlled, especially at the wound site Also make sure that the wound site is clean. regular dressing and disinfection is needed. Your doctor would have probably prescribed antibiotics. They should be taken regularly as prescribed. I hope this helps you.
