(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.
