In a couple of months, the ulcer will go through three stages - exudation, granulation and epithelialization.
Exudation usually lasts a couple of weeks. Perifocal edema, inflammation around the perimeter of wounds, tissue neuroses, an unpleasant odor - this is an incomplete list of what is happening with the ulcer at this time. The risk of getting an infection is high. By the way, this compound word denotes the processes of release of an inflammatory fluid, in this case, pus, into the wound cavity.
Granulation will take two to three weeks. The ulcer will begin to gradually clear of necrosis, edema subsides, purulent discharge decreases, and the inner surfaces of the wound become covered with granulations. This period is often referred to as repair, regeneration, and new tissue formation.
Epithelization is a long and individual process. In about a month, the wound will gradually cover with new skin or form a scar.
