A herniated or bulging disc involves the soft cushion of tissue between the spinal bones to push out of place. People with a herniated disc will often experience lower back pain, neck pain, and difficulty bending the back. The pain from a herniated disc may get better with gentle exercise and painkillers. The condition is usually caused by aging, incorrect form while exercising, or lifting heavy objects the wrong way.
A study conducted on the efficacy of LLLT for patients with herniated or bulging discs found that the treatment was effective for neck and back pain caused by cervical disk hernia. Postural training and physical activity reinforced the benefits of LLLT.
