Cuts, or lacerations, are openings into or through the skin. Cuts may just go through the skin or they may go into the deeper fatty or muscle tissues. Scrapes and scratches are areas of damage to the upper layers of skin. They may go into the deeper layers of skin and they may bleed, but they don't gape open to expose the fatty tissue beneath the skin.
Cuts can occur from a variety of things. Most often they are caused by something sharp like glass or sharp metal that slices into your skin. Sometimes things that are blunt rather than sharp come into contact with your skin with such force that the skin tears. Scrapes and scratches occur when something harder than your skin comes into contact with it: for example, when you fall onto the sidewalk or when a nail or pet scratches you.
The symptoms are:
Your healthcare provider will ask about what happened and examine you.
The treatment of a cut depends on the depth of the cut. Shallow cuts that go just into the upper skin can be treated at home just as you would a scrape or scratch (see below). Deeper cuts may need to be closed with skin glue, stitches, or staples. There are no hard and fast rules about this because the treatment depends in part on where the cut is. For example, you may want a cut on your face to be closed to lessen scarring. If it were on your foot you might not care so much about scarring. It also depends on how long and deep the cut is and how it happened. For example, very dirty wounds like animal bites are generally not closed because they are more likely to get infected.
When you have a scrape, scratch, or minor cut:
Call your healthcare provider right away if:
If you have any question about whether a wound needs to be treated, get it checked by your provider.
If you have a cut that glued shut, you can just wait for the glue to wear away. See the instructions that were given to you about wound care after gluing. If your wound was stitched shut and the stitches do not dissolve on their own, you will need to have them taken out. (If you can see the stitches going through your skin, they are not the kind that dissolves.) Your healthcare provider will tell you when you need to return to the office for removal of the stitches or staples. Depending on where a cut is, it will take about 5 to 14 days to heal.
Your scrape or scratch will probably heal in a week or so, depending on how large it is (the larger it is, the longer it takes). If you have other medical problems, it may take longer to heal. If your wound hasn't healed after 2 weeks, call your healthcare provider.
