You should look into seeing a chiropractor. I work for one and we have many people come in with DDD. We use something called spinal decompression which stretches your back for a certain time and at a certain pressure. This combined with chiropractic adjustments can really make a difference in your health.

Also at most chiropractic offices they do accupuncture, this is also a great way to help with pain and get you into better health.
