If the injury swells too much, the bump could signal a bone or joint injury. And, if the bruises keep coming too fast and furious, it could signal a more complicated medical condition.
Bumps and bruises are damage that occurs in the soft tissue under the skin. Under the following conditions, there is no need to call for medical assistance when a person suffers a cut, scrape, bump, or bruise:
Bruises on the hands, fingers, feet, and toes can cause more problems than those that occur on knees, shins, or arms. Your hands and feet are a complicated network of motor functions, nerve endings, and flexibility. Any problems in these areas can cause a disability. For example, stubbing a toe might make walking difficult, or a damaged finger might keep you away from the computer. If you or someone around you experiences more than minor swelling or bruising after bumping into something or falling down, call your physician.
Here are simple first aid procedures for treating minor scrapes and cuts:
A cut and a bruise, with or without swelling, are basically the same thing, except that one occurs at the body's surface, and the other occurs under the surface, in the soft tissue below the skin. In fact, the ugly black and blue marks you see when you bruise are really blood clots that form under the skin. The worse they look, the more they are clotting and healing.
But because bruises (and their potential partner, swelling) don't break through the skin, there is a difference in first aid treatment. Follow these steps for treating bruises.
A blister is a built-up, fluid-filled irritation under the surface of the skin. A blood blister is a red blister that contains blood. A fever blister is another name for a cold sore or a herpes simplex at the lips. None of these are dangerous, but if they are accompanied by excessive pain or fever or if they grow larger, you should see your physician for proper drainage and possible medication.
Hemorrhaging is another word for uncontrollable bleeding. Because it is caused by breakage in blood vessel walls, it is usually internal, which means you can't always tell that a person is (literally) bleeding to death!
A slight amount of bleeding that creates a bruise under the skin is one thing, but hemorrhaging is quite another. Internal bleeding can be serious and can affect one's vital organs. The symptoms of internal bleeding are similar to those of shock:
Unfortunately, first aid procedures will not stop internal bleeding. The best thing to do is to call for help immediately. Then proceed with the first aid steps for shock (see Performing Mouth-to-Mouth Resuscitation).
