What's a way to ease neck pain and shoulder pain?

Approp. Diagnosis: The key to treatment would be to first make the appropriate diagnosis as the source for your pain. I would find a good local orthopaedic surgeon who specializes in the treatment of shoulder pathology.

Therapy/medication: Initially a short course of anti-inflammatories, muscle relaxers, and massage can help. Physical therapy can be prescribed to work on posture, gentle exercise, traction and modalities such as heat and ultrasound. Sometimes injections can be used to help decrease the pain and facilitate therapy. See your physician if your pain lasts greater than 2 weeks.
