What treatment options are available for back pain and muscle spasms?

Many options: You need to have a diagnosis first, whether it is a simple strain/sprain, fracture, disc herniation, spinal stenosis. Assuming the condition does not need immediate surgical treatment, simple first treatments include chiropractic manipulation, massage, traction, physical therapy, acupuncture, medications, core strengthening exercises. If no response, consider injections and subsequently surgery.
