Hello,

I saw this part and "burning/sharp pains in my neck and shoulder blades" - I have a few questions, since you state the syrinx isn't the cause of pain.

What levels are the 3 herniated disks at?
Is the DDD at all levels or or certain areas?

If the drs don't believe those are the cause of your pain - could it be from some sort of repetitive injury?
What kind of work do you do? desk/computer/repetitive/sports injuries/falls/previous whiplash??

There is a condition called thoracic outlet syndrome {TOS} that can cause neck, shoulder, upperback and even elbow and arm/hand pain & symptoms. It generally will not show up on tests or MRIs, just like most repetitive strain injuries. If this might fit we do have a TOS forum here for more info.
