Step on a nail and your scream will let the whole world know. And the whole world will tell you to get that looked at immediately. Puncture wounds to your feet need prompt care to avoid complications. If the object you stepped on is small, like a needle or a splinter, carefully remove it and apply gentle pressure to your foot to stop any bleeding. If debris is left in the wound, you may need professional help to remove all the pieces. Use soap and water to clean the puncture and minimize your infection risk. Apply an over-the-counter antibiotic and a clean bandage to protect the hole. You may need to pad the area around the wound to protect it from pressure, too.
