A bruise is a mark on your skin caused by blood trapped under the surface. It happens when an injury crushes small blood vessels but does not break the skin. Those vessels break open and leak blood under the skin.
Bruises are often painful and swollen. You can get skin, muscle and bone bruises. Bone bruises are the most serious.
It can take months for a bruise to fade, but most last about two weeks. They start off a reddish color, and then turn bluish-purple and greenish-yellow before returning to normal. To reduce bruising, ice the injured area and elevate it above your heart. See your health care provider if you seem to bruise for no reason, or if the bruise appears to be infected.

Your ear has three main parts: outer, middle and inner. You use all of them in hearing. Sound waves come in through your outer ear. They reach your middle ear, where they make your eardrum vibrate. The vibrations are transmitted through three tiny bones, called ossicles, in your middle ear. The vibrations travel to your inner ear, a snail-shaped organ. The inner ear makes the nerve impulses that are sent to the brain. Your brain recognizes them as sounds. The inner ear also controls balance.
A variety of conditions may affect your hearing or balance:
- Ear infections are the most common illness in infants and young children.
- Tinnitus, a roaring in your ears, can be the result of loud noises, medicines or a variety of other causes.
- Meniere's disease may be the result of fluid problems in your inner ear; its symptoms include tinnitus and dizziness.
- Ear barotrauma is an injury to your ear because of changes in barometric (air) or water pressure.
Some ear disorders can result in hearing disorders and deafness.
