I have neck arthritus are their certain exercises to eleviate stiffness?

Ask your primary to send you to physical therapy for a few sessions to teach you a home exercise program. If you have ben cleared, here is a site with some decent exercises: http://www.Spine-health.Com/conditions/neck-pain/neck-stretches.
