Hello and thanks for writing in. Management of diabetic foot (ulcer) involves a multi-pronged approach. It includes care of the wound- dressings, treating any infection, control of blood sugar, and investigation for peripheral arterial insufficiency (arterial blood flow to the foot and leg). Please do not delay going to a doctor- a general surgeon/specialist. Also prevention of ulcers is a very important aspect- eg. daily foot inspection, gentle cleansing, prompt treatment of minor wounds etc. Only after inspection of the wound/infection, is it possible to plan the treatment. Do not worry, and see a specialist as soon as possible. Hope this is helpful. Take care and do write in if you have any queries.
