Make an appointment with your rheumatologist right away if you start having neurological symptoms, like tingling, weakness, and numbness in your arms, hands, or fingers. Also call if you have muscle spasms in the neck and shoulders, trouble walking, loss of balance, headaches, and grinding or popping sounds when you move your head. If imaging tests show instability, the next step is a referral to a neurosurgeon for possible neck-fusion surgery. If you are scheduled for any other surgery prior to that procedure, Dr. Bhatt recommends you contact your rheumatologist so he can consult with that team. The way your neck is moved during anesthesia can damage an RA-affected joint.
