I had DRX 9009 decompression treatment at a chiropractic office. It consisted of a large number of appointments at a cost of approximately $4500. I’m not entirely sure that it was as successful as the hype. In addition they wanted to suck me into a whole series of treatments when the decompression was over. I didn’t continue. I guess if you’re desperate it’s worth a try. My back still goes out occasionally so it’s not a cure.
