Prevention
By Mayo Clinic staffYou can't totally prevent pyoderma gangrenosum. If you have the condition, try to avoid injuring your skin. Injury or trauma to your skin can provoke new ulcers to form. Although not entirely effective, control of any underlying condition that may be causing the ulcers may be of help.
