Diabetic ulcer on big toe. The ulcer (open sore) is on the outer side of the big toe. The skin is yellow, thickened and swollen. The centre of the ulcer has burst, and the sore is red and weeping. Ulcers are found on the skin or on mucous membranes and they destroy the surface tissue. Diabetes is associated with damage to the peripheral blood vessels and neuropathy (nerve damage). This can lead to ulcers forming on extreme areas, especially the feet, but with care these can be avoided. Ordinarily a corticosteriod drug is prescribed to reduce the inflammation, but this drug cannot be taken by diabetics. An antibiotic is taken to combat the infection.
