Does the foot injury need a gauze bag?

Hello! According to the description of your illness, it may be a foot injury. Generally, hydrogen peroxide and physiological saline are enough. Perform local irrigation and then perform local debridement with iodophor or alcohol. If the injury is serious, local suture should be performed. And use antibiotics to prevent infection. Abrasions can be treated with local anti-infective drugs without dressing. If the wound is debrided and sutured, local dressing should be performed.
