I have pain in arm from neck to finger tips since having stitches removed after carpal tunnel surgery ?

Neck problem: CTs can hurt all the way up to the shoulder but not the neck. Think Cervical radiculopathy. What did the pre-operative EMG show?

Pain and numbness: If amount of nerve compression was severe and that it takes time for the nerve to feel better. It may be that the nerve was irritated by the surgical process and that the nerve is a bit more sleepy. In severe cases often it takes longer (far longer than it does for the incision to recover) to exhibit improvement and at times full improvement may not be possible. Talk to your surgeon about this.

Neck pain: You may have a pinched nerve in the neck that was mimicking the carpal tunnel syndrome. Alternatively, releasing the median nerve at the wrist may have uncovered the pinched nerve in the neck. You may need an MRI of the cervical spine to confirm a pinched nerve in the neck. Physical therapy, transcutaneous electrical nerve stimulation, and neck traction may relieve the pain in the neck and arm.
