I Have Had For The Past 4 Years Ongoing Muscle

I have had for the past 4 years ongoing muscle pains on only the right side of my body. The right side of my neck gets tense, my head hurts on the right, my right arm, my right upper back, lower back, my right buttocks, my right leg and all the way to my right Achilles tendon. Even my chest starts to feel tense on the right side. I can only describe it as a sore muscle, like after a good workout. But it's always there. And if I do try to work out thinking maybe that will help the muscle pains get worse. My doctor did an xray of my cervical spine and the middle spine(forget what it's called). She said it showed significant neck muscle spasm and a tiny bit of arthritis in my neck. Is the muscle spasm a cause or the effect of something else that's wrong with me? I'm just wondering if I should see a neurologist. She wants me to either have a chiropractor, acupuncturist, or massage therapist to try something. What should I do?
