I have suffered from severe back pain for a number of years. I visited doctors, neuro-surgeons, and physiotherapists for years, but nothing really helped. At times I even had to spend a day or two in bed with excruciating pain. I started using this App after downloading another which I found to work exceptionally. After two weeks of listening to the App daily, I am finding relief from my persistent back pain. I am now having almost painless nights, can sleep well, and wake up well :) I am also able to do things I had stopped doing years ago without getting a recurring back ‘crisis’. In a couple of weeks I am feeling much better than I was before, after years of medication. I highly recommend the App. It works amazingly well for me. Really exceptional. Thank you Darren.
