A once-in-a-lifetime jab may treat back pain. In a new trial, injections of lactic acid a syrup-like substance formed in sour milk and found naturally in our bodies are being given to 120 patients with lower back pain caused by disc problems.
The researchers say that the jab will make the discs, which sit between the bones (vertebrae) of the spine, tougher and more resilient and could remove the need for surgery for many.
Around eight in ten people have back pain at some point, and up to one in four cases is caused by disc problems.
