Ulcers need to be kept clean. Unwanted crusts and dried pus can be removed by soaking the extremity in lukewarm water for five minutes. Allow to dry before applying bandage. Although electrically-heated socks and gloves are ideal for most patients, if you have an ulcer, the heat may, in fact, irritate it. So be especially careful with any heating aids when you have an infection, not to mention that adding heat makes the throbbing that much more intense.
Ulcers are slow to heal but almost always eventually close.
Nothing works rapidly or consistently enough to convince all patients and doctors that the best single treatment has been discovered. The cure for ulcers will be that which can restore normal blood supply. In the meantime, with good common sense and patience, ulcers will generally heal. Alternate small amounts of hydrogen peroxide or Epson salts in warm water. Soak 5-10 minutes.
