If it can help determine between nerve pain caused by a disc and actual muscle pain, then it's a huge benefit to patients and doctors. I too have severe back pain, but the doctors have a difficult time determining what percentage of my pain is from my disc problem vs. what is coming from trigger points (muscle spasms). It's very frustrating as a patient because pain meds do not help with this kind of pain, at least in my case. With everything, you have to observe with caution, but I can see a great need for this device if it performs as advertised. GLTA!
