How long should it take for a cellulitus ulcer to heal and disappear?

Varies: In the ideal situation it would take about 10 to 14 days. There are many variables that contribute to the rate of healing for each person. Because of genetics, some people heal faster than others. Chronic diseases like diabetes and peripheral arterial disease can delay wound healing. Poor nutrition and poor wound care can also delay cellulitis and ulcers from healing. Smoking = poor wound healing.

treat the cause: The question is, what caused the cellulitis and more, which came first? Cellulitis is an inflammation of the skin but finding the cause is most important. If you did not have a fever or elevated white count, then infection is very unlikely. A more common cause of your condition would be due to pain disease. Get to a wound care center for the appropriate diagnosis and treatment.
