Further evaluation: Firstly depends on what they used to confirm injury - if CT or X ray used, not too good for ruling out soft tissue / disc injury. If MRI done and was clear then may need evaluation / treatment for muscular/fascial /ligament origin pain - such as therapy, massage, trigger point treatments. Basically needs comprehensive eval by your doctor

Followup: Definitely need to follow up. Usually if you were seen in the emergency room you would have been given a followup with the orthopedic surgeon or neurosurgeon on call. There are some injuries that require further testing to be diagnosed such as an MRI. Make sure you follow up.
