Disc hernia occurs when the soft central portion of an intervertebral disc bulges out beyond the damaged outer rings of the disc. Patients present with back pain, leg pain, or lower extremity weakness. Treatment is individualized but may include NSAIDs, narcotics, nerve medications, cortisone injections, or minimally invasive low-intensity laser therapy (MILLT). A study compared MILLT to conservative treatment using NSAIDs in 600 patients over 5 years. Results found that 76% of MILLT patients reported reduced pain within 4-5 treatments, and 85% saw decreased disc herniation on MRI after 3 months, indicating MILLT may produce longer-lasting relief than other treatments.
