Acupuncture. Could de a good compliment to physical therapy, and medications.
Yes. There is good evidence that acupuncture and acupressure may help with neck and back pain. These work in a different way than Western medicine treatments and the combination is usually better than one or the other alone. You should look for a licensed acupuncturist or a medical doctor who has taken an acupuncture course for best results.
Maybe. Again, I am not a fan of cam, but whatever modalities (within reason) is worth a trial.
