On my mri of the cervical spine report is written the following "FINDINGS: There is posterior disc herniation at the c5-6 level.This ceates moderate canal stenosis and extends posteriorly to come in contact with the cord.Findings efface the anterior thecal sac and cause cord compression.This is a somewhat broad based disc herniation and also appears to effect both neural foramen.At c3-4,there is a very small posterior central disc herniation which does not create significant canal or foraminal narrowing.The remainder of the cervical disc in intact.The posterior elements are maintained.The paraspinal soft tissues appear normal.IMPRESSION: LARGE POSTERIOR CENTRAL DISC HERNIATION AT C 5-6.VERY SMALL POSTERIOR CENTRAL DISC HERNIATION AT c4-5." I had arms and legs EMG/NCS which was normal,but I still have total nubness in my thumbs (not in both hands at the same time),other fingers and hands in general for several minutes upon awakening in the morning.During the day I do not have total numbness in my fingers and hands,but my palms (skins) do feel differently.There is a different feeling (spasms,tiredness) from elbow to hands during the day,heavines on the back of neck,spasms in feet,sometimes total numbness in feet when sitting and sleeping in chair for prolong time. 1. Are the above symptoms(especially total finger and hand nubness for a couple of minutes upon awakening in the morning) caused by c 5-6 disc (bulging,protrusion) herniation? 2.Do I have to have c5-6 disc surgery and when is surgery indicated(by what symptoms)? 3.I talked to one neurosurgeon and he said that he would do surgery only when there is progressive weakness in arms,but not for numbness.Do you agree? 4. What is the likehood (in %) of these 2 herniated discs causing paralysis from neck down to feet (A) if they are not operated on and (B) if they are operated? 5. What should I do to prevent these discs from getting worse,for example should I stop fast walking on treadmill,watch how I position my head during sleep,carrying groceries etc? 6. Can I have cervical endoscopic discectomy or even microdiscectomy for the above discs as opposed to traditional ACFD?If no why not? 7. What's ACFD surgery success rate,for instance does nubness go away after surgery?If no why have surgery? 8.What's the difference between protrusion and extrusion discs and are protrusion discs considered herniated discs?BTW I am average 50 year old male.Thank you
