Cuts: Severed skin. Washing a cut or scrape with soap and water and keeping it clean and dry is all that is required to care for most wounds. Putting alcohol, hydrogen peroxide, and iodine into a wound can delay healing and should be avoided. Seek medical care immediately if you think that you might need stitches. Any delay can increase the rate of wound infection. Any puncture wound through shoes has some risk of infection and should be seen by your healthcare professional. Any redness, swelling, increased pain, or pus draining from the wound may indicate an infection that requires professional care.
