Wrapping the remaining part of your leg (residual limb) keeps it from swelling. And wrapping shapes it so that it fits more comfortably in a prosthesis. You'll probably need to keep your limb wrapped (or keep it in a “shrinker sock”) at all times—except when you bathe or wear a prosthesis. If it's hard for you to wrap the limb yourself, have someone wrap it for you. You may want to wrap it before you put on your underclothes.
