His leg is probably wrapped up due to that nasty fucking fluid leakage fatties get due to poor circulation. They use compression wrappings to try and push that shit in so they don't end up with huge weeping ulcers. I had a friend that got fucking huge (600+ lbs) with this problem. You are supposed to change the wrappings like every 4 hours to prevent infections. He did it like every other day, and would just leave his nasty, dirty, infected mummy wrappings laying wherever (including my friend's dining room table). His legs looked like a fucking horror movie. He can't wear shoes anymore, because the swelling above his feet has gotten so bad it looks as though he has a pair of watermelons where his ankles were. I tried to help him, tried to get him to change, offered to create a diet plan and even cook and deliver it. I offered him a pool to work out in. I literally handed him the means to fix things (as much as they can be fixed) and he threw it back in my face. So fuck him. He'll be dead at 35, and doesn't have any friends left to give a shit about it.
