My mother who has had diabeties since age 5 now has legs ulcers for almost 2 years. what to do?

Serious!: Leg ulcers in a diabetic is a big concern. If the ulcer becomes infected it could extend quickly without appropriate treatment. She should be seen by a team of specialists including wound care and internal medicine. She will likely need wound debridement, antibiotics, leg artery ultrasound, and possibly MRI of the area to rule out bone infection (osteomyelitis).

Heal a leg ulcer: There are many types of leg ulcers: venous, arterial, neuropathic, trauma, surgical, and those from dozens of different dermatologic problems. Please see wound specialist for further direction as diabetics can get all of these.
