Scientists say new ‘acid’ jab could beat back pain caused by disc problems for good

In a new trial, injections of lactic acid are being given to 120 patients with lower back pain caused by disc problems. Researchers say the job will make the discs which are situated between the bones (vertebrae) of the spine, tougher and more resilient, and could remove the need for surgery for many patients.

Around 80 per cent of people suffer from back pain at some point and up to 25 per cent of cases are caused by disc problems.

Current treatment options range from physiotherapy and painkillers to steroid injections and surgery to fuse the spine or remove the damaged disc.

Lactic acid is a natural by-product of energy production in the body, building up muscles after exercise and is thought to be what makes them ache. Its use in alleviating back pain is based on the idea that it encourages the development of collagen, which makes the disc tougher and more resilient. Orthopaedic surgeons have long reported that patients who experience back pain related to disc problems often have less pain as they age, as the collagen becomes tougher and the discs are able to provide more support to the spine.

Commenting on the study, Ian Harding, an orthopaedic consultant at North Bristol NHS Trust, says “Back pain is caused by many different diagnoses, of which a minority will be caused by the disc itself. Any treatment that can help and avoid more invasive high-risk treatments warrants investigation.

“Studies such as these may lead to large trials and a better understanding of the problem.”
