I am a retired chiropractor, I fractured my 5th cervical vertebrae in 1995. I have 3 herniated discs (severe) in my lumbar spine due to osteomyelitis. I found this wonderful piece of equipment a few years ago and it has done wonders for me. I’ve gone through severe sciatica along with muscle wasting in my lower legs. I started using this device everyday and the results are miraculous. I tried inversion tables and that actually aggravated my condition. I highly recommend Nubax to all practitioners and anyone who has back problems.
