What are the current treatment options for chronic pain from osteoarthritis in cervical spine with decreased range of motion in neck ?

Dilemma: I hope there was a good answer, but there is none. Analgesics will help, but may not be adequate. Nsaids long-term are in-advisable due to adverse effects. Cox-2 inhibitors are better but expensive and not good for heart or kidney patients. Steroids may be injected by a spine surgeon. Surgery is also available. Opioids cause dependence.

Many options: There are various topicals or compounded creams that help with pain and inflammation. There are many oral meds: tylenol, (acetaminophen) weak to strong nsaids, special nsaids like celebrex, steroids, opiate pain relievers, mood medicines like cymbalta. Some supplements might help: quercetin, turmeric, msm, glucosamine chondroitin. Also, injectable steroids or prolotherapy. Physical therapy can help too.

See below: As per dr kumars answer but also consider gabapentin/pregabalin , Cymbalta (duloxetine) or similarly working agents.
