Chronic low back pain (LBP) caused by intervertebral disc herniation was reported in the 2010 Global Burden of Disease study to be the main reason for years lived with disability. It causes significant personal, social, and economic burdens. Many of those who suffer from LBP find conventional medical treatments to be unsatisfactory for treating their pain, so they are increasingly resorting to complementary and alternative medicine (CAM) therapies. Given that the population is aging, there is an urgent need to characterize the combinations of complementary therapies that yield the best outcomes and treatments, even for prolonged periods. This observational study aimed to evaluate the effect of ultramicronized palmitoylethanolamide (umPEA) + CAM (daily functional rehabilitation + decontracting massage) therapies on chronic pain in patients suffering from multiple herniated discs in the lumbar spine.
