People I would recommend the DRX 9000. My friend went to a chiroprator and he recommened this treatment. No shots no surgery. It helps regenatate the disc with your own white blood cells and nurtients from your body. The other people I asked in the waiting room said that they feel so much better and can do all the activities they once did with out the cripiling pain. One women in the said that she was doing her last treatment with the machine (after already having the surgery years before) and she is finally off her pain meds and no pain.
