Cut—This is a type of wound where your skin is sliced open by a sharp plane. It could be small and shallow like a paper cut or large and deep, as is the case with some knife cuts. Not all cuts are smooth—some may be jagged depending on the instrument that has cut you, and the pain levels vary depending on the size and depth.
Blister—A type of wound wherein fluid collects in a bubble under your skin. This may or may not be open because blisters burst, and they come in different sizes. If the skin isn’t broken, the blister is considered sterile.
First aid for minor wounds
The good news for minor wounds is that most of them can be safely treated at home. With proper first aid, your wound should recover in a few days without any problems.
Stop the bleeding. If the wound is bleeding, you’ll need to address that immediately before doing anything else. Get a clean and dry absorbent material that won’t leave residue—a towel or a handkerchief will do if you don’t have a bandage handy—and apply pressure to the affected area for several minutes to give time for your blood to clot. It also helps to reduce the blood flow to that area—this is easy to do if the wound is on your limbs. Lift your arms above your head or lie down and raise your legs above your heart level to reduce the blood flow3.
