Yes, we have seen this in both ADR and fusion patients. It actually may not be related to the surgical site, though it sounds probable. Are you sleeping more deeply...when you are sleeping?Are you dreaming?
I wonder if the soft tissues in your throat are inflamed from the trauma of surgery and intubation. If this is the case, it should get better. but we have many cervical spine patients in this community....
...a little help, cervie friends?
BTW: What did your doc say about the use of NSAIDs? I think this is an important topic for ProDisc C patients to have with their surgeons (see or search for related discussions).
