When you dislocate a joint it actually means your joint slipped out of place. It is usually caused by a sudden blow or fall or any other trauma to the joint. Dislocations happen more often in contact sports, such as football and hockey, and in sports where you are likely to fall such as downhill skiing, gymnastics and volleyball. A weakened joint by caused by overuse can also be easily dislocated. When you dislocate a joint it probably will not function properly. You should get medical treatment as soon as you are able. Symptoms can vary from swelling and intense pain to being unable to use the joint. Sometime you can even see that the joint is dislocated or out of place. You may experience tingling or numbness near the injury usually it will heal with pain medication to reduce the pain and ice to reduce swelling. Occasionally surgery may be needed to repair or tighten stretched ligaments. Gentle manipulation and reduction may be needed to put the joint back in the right place.
