A “slipped disc” is an old term that in today’s world unfortunately does not translate into an accurate description of the pathology. “Slipped disc” could mean a disc tear, a herniaton or even a degenerative or isthmic spondylolisthesis (see website for information on those disorders).
Transforaminal injections, if performed with injectable steroids are a good treatment for the pain generated by many spinal disorders. I am not a fan of ozone as this is a corrosive agent and can injure nerve roots.
