Are there specific exercises for neck arthritus?

Neck arthritis: Gentle stretch of extension, flexion, lateral bend, lateral rotation, as well as shoulder shrugs. Watch your posture.

I agree: If you are uncomfortable doing these exercises, request a few physical therapy visits. A therapist can ensure the proper technique of each exercise. Best of luck!
