 Well, the best way is to come and have your foot examined. If you're a diabetic, one of the earliest things you should do is have a good thorough foot examination by a podiatrist. I'm thinking of poor circulation. Does that mean that I'm going to notice that my feet are really cold in the wintertime perhaps? Do they get discolored? They can feel colder. They can also be discolored. A lot of patients are just not aware that they have the circulation issues, especially if they're really not paying attention to their feet. Or if they've got numbness, they may not notice that they've got some of those complications such as poor circulation.
