Some of you have posted about this so let me give you the facts. The paper with results of the first trial was published in 2008. Funding for a second stage was not granted until 2013. Recruiting for this will not be completed until Dec this year. Trial will not start until sometime in 2016 and is for 44 months, that makes it 2020. They will then need to study the results and publish another paper. 2021. I have this morning received an e-mail from NIHR which states that a third stage trial is required so based on the time between publication of first and second stage papers it will not be until 2034 (how many of us will be dead by then) whether we know or not if it will be approved for general use and remember it's not a cure just away to reduce pain levels
