Because my fusion is in the thoracic I never felt any loss of range of motion. I have a BASMI score of 1 of less despite the fusion. Both my neck and lumbar spine have no signs of AS yet.

I am considering the following as my cause of neuropathy

Spinal cord edema/myelomalacia
Toxic - Humira damage
Sjorgens - I don't have dryness anywhere though
Lyme
Lupus
Vasculitis
CFS
CMT
Anxiety (generalized)

My issues still come and go but the intensity has gotten worse over time.
