(HealthDay News) -- A dislocation occurs when two bones that meet at a joint become separated. The ADAM Encyclopedia says this may damage nearby ligaments, nerves and blood vessels.

ADAM says it may be difficult to distinguish the following symptoms from those of a broken bone, both of which require immediate treatment. It mentions these potential warning signs of a dislocated joint:

• A tingling sensation or numb feeling in or around the joint.
• Severe pain, particularly when trying to move or put weight on the joint.
• Limited range of motion.
• Swelling or bruising.
• Unusual color or shape.
• A joint that obviously looks as if it's distorted or out of place.
