You have a large disc herniation at C4-5 above your fusion from C5-7. This is causing significant spinal stenosis and spinal cord compression with cord injury (“suggestive of edema related to cord compression”).
The cord is further compressed with neck motion. You need to be placed in a cervical collar now with your head in slight flexion (this is the position of least cord compression). You need a surgical consultation as soon as possible to prevent further cord injury.
