An ankle sprain refers to an injury to one or more of the ligaments on the outer portion of the ankle. Ankle sprains can range in severity from mild ligament stretching to more serious ligament tearing. Swelling and pain frequently accompany an ankle sprain.

Swelling often indicates a condition or damage in the body that needs medical attention. Swelling is most often associated with flesh injuries or damage to structures in the body, such as the bones, tendons and ligaments. But some forms of swelling can indicate serious conditions affecting the cardiovascular system.

Your AC joint, technically called your acromioclavicular joint, is found in your shoulder where your scapula and clavicle meet. The AC joint can be damaged through a chronic condition such as arthritis, but in most cases injury is due to separation of the joint. AC separation is rated on a grading system.

Performing CPR properly can mean the difference between life and death. CPR, which stands for cardiopulmonary resuscitation, is an emergency procedure done when someone’s breathing or heartbeat has stopped. CPR techniques vary depending on the age or size of the patient.

Swelling of the lip can be caused by an allergic reaction or trauma to the area or, in rare cases, as a result of certain diseases such as leukemia or Hodgkin's disease. Once you identify the cause of your swollen lip, you can begin reducing the swelling through at-home treatment.

A sprained ankle, one of the most common sports injuries, occurs when a player stretches or tears a ligament. While the ankle contains many ligaments, most sprains involve the lateral ligaments on the outside of the joint.

Dehydration is a medical condition caused by inadequate fluid levels within the body. If left untreated, dehydration can be a life-threatening condition—especially in infants and toddlers.

Finger splints are sometimes used to hold your finger in place to keep it from moving, such as when it is sprained or broken. They can also be used to increase the range of motion of a finger that is stuck in a bent position and needs constant stretching. A variety of splints are available to treat finger injuries.

People of all ages can develop dehydration from excess fluid loss, but newborns, in particular, are more at risk of developing the condition. Dehydration is the result of losing more fluids--through sweat, vomiting or diarrhea--than you are taking in.

A burn to the top of the foot can be caused by contact with hot water or grease, from chemicals that fall on the foot or any hot object that touches the sensitive top surface of the foot.

If you are tired, achy, running a low-grade fever, coughing up mucus and generally feeling blah, you may have acute bronchitis, or a chest cold. Bronchitis occurs when the bronchial tubes in your lungs become irritated and inflamed.
