Some injuries and illnesses require X-rays, but if an injury or illness is or could be life-threatening, it’s necessary to go to the ER (emergency room). The following are some life-threatening or potentially life-threatening injuries and illnesses that may require X-rays and care at the ER: - Major concussions - Major/compound fractures - Sprains that have completely torn ligaments or ligaments that have separated from a bone There may be other injuries and illnesses that require X-rays and care at the ER. However, if an injury or illness is non-life-threatening, then it’s best to go to urgent care for X-rays and care. For example, you can go to urgent care for a minor concussion, simple fracture, or minor sprain. Urgent care can see you right away with no appointment necessary.
