"What should I do if I see drainage on my sock? A diabetic patient should seek attention by a podiatrist or another medical professional immediately. Drainage means there’s an open wound. With any breaks in the skin, there is potential for bacteria to enter into the body. Diabetes can affect a person’s ability to fight off infection by inhibiting the body’s immune system. The sooner an open wound is found and appropriately managed, the less likely for problems to develop such as slowed or non-healing of the wound, infection, need for hospital admission, or the need for surgery. Diabetic foot wounds should be treated as an emergency."
