I am experiencing neck pain, wrist pain, hand pain, arm pain and shoulder pain. The following also describe me: Finger tingling, Popping or snapping sound from shoulder joint, and Arm weakness. What should I do?

See a doctor. It is not feasible to provide a meaningful opinion without examining you and your symptoms warrant evaluation by a physician. Your description suggests an auto-immune inflammatory disorder and such issues can be treated.
Wish you good health!
