For how many days bandage is used on wounds n scrape like cut i have shoe bit on my back side of foot will i cover it for how many days i cover it ?

Depends on many thin: The purpose of wound dressings is to absorb xs exudate (fluid) until wound heals. By itself, the dressing will not heal a wound, but an improper dressing can impede it. The length of time to heal a wound depends on many factors, including cause, ur underlying health, extent of injury, & whether or not improper care is being taken. If wound is caused by a shoe that doesn't fit, don't wear it. TTYD.
