Diabetic foot sore
Often, a ulcer that is open for an extended period becomes infected.
But, because the pain usually associated with a sore is absent, there may be rapid and dangerous progression of the underlying infection. In many cases, this leads to amputation
of either toes or part of the foot. In the worst case scenario (short of fatal sepsis
), an untreated diabetic sore can lead to amputation of the leg.
