Usually last one. Unless you have a tumor, infection, an unstable fracture or one with neurologic issues, a myleopathy, or a progressive neurologic dysfunction caused by spinal stenosis or a disc herniation, surgery should be final option after: activity modification, exercise/physical therapy, time, medication and where indicated: a soft cervical collar, pain management, massage, acupuncture, local heat, traction.
No. It is actually the last resort. You should first try physical therapy and even pain injections prior to undergoing surgical procedures for correction in most cases.
