I am unclear as to the surgery as initials are normally not used to describe surgery.
I assume it might be a vertebral corpectomy with allograft and plate.
Difficulty with swallowing is not abnormal after a corpectomy. This problem can take up to six months to resolve. You might try thick liquids (yoghurt or “shakes”) until the problem resolves as thicker liquids are easier to swallow. Sometimes, oral steroids can help to reduce this problem.
Upper back numbness is unusual for a post-operative symptom. A dull ache in this region is typical if the graft distracts the degenerative area. The stretch of the posterior ligaments will cause this dull ache.
