Narrowing of C3-4 and C5-6 is typically indicative of cervical degenerative disc disease. See section on website regarding this. Read at the section on “When to have neck surgery” and you will see that you are currently far away from that decision.
You need a good rehabilitation program and not with a trainer but a well qualified physical therapist. You might also benefit from injections.
If there is no nerve or cord compression, then there is no penalty if you don’t have surgery now.
