As the uploader of this channel, not the guy in this video, I feel the exact same way as him as I have also suffered from chronic lower back pain for 20+ years until I started CBD.
My back pain went away in the fall of 2015 almost over night after I added CBD to the picture. Some of the strains I consume now are Cannatonic, Warlock, Afghani & Sweet Skunk CBD and Durga Matta II. This is not to say that THC does not help with back pain as it does as well. My problem was the inflammation that would never go away.
The man in this video Tomas Harner has endured chronic back pain for 30 years as a result of accidents. In the last 10 years, he said his condition became worse, and doing simple tasks like putting on shoes were becoming difficult. Within the first week of consuming cannabis oil, the sharp pains which inhibited his movements were gone. Tomas maintains awareness of his injury, but the vast majority of his pain has disappeared and his range of movement has improved dramatically. He believes that taking more oil will eliminate remnants of pain.
