Chiropractors use several techniques to treat herniated discs, including manipulation under anesthesia, pelvic blocking techniques, and flexion-distraction technique. Manipulation under anesthesia involves stretching and manipulating the affected spine while the patient is sedated. Pelvic blocking techniques help alleviate pain from affected nerves of herniated discs. Flexion-distraction technique is a gentle and pain-free procedure beneficial for patients with severe spine pain.
