Bulging discs in the lumbar spine at 2-3, 3-4, and 4-5 are mainly treated conservatively, while some cases may require surgery. The decision depends on whether there is nerve damage and the degree of impact on life and work. 1. Conservative treatment: When the symptoms of lumbar disc bulge are not obvious, conservative treatment is recommended, which can be treated by bed rest, traction, physical therapy, massage and other physical therapy, or taking pain medication such as ibuprofen under the guidance of a doctor. Normally, avoid excessive bending and weight bearing, and strengthen the lumbar protection. 2. Surgical treatment for special cases: If multi-segment bulging discs are accompanied by spinal stenosis, symptoms are obvious and conservative treatment is ineffective, surgical treatment can also be considered to relieve the compression in the spinal canal and effectively improve the quality of life. For lumbar 2-3, 3-4, 4-5 bulging discs, it is recommended to consult a doctor and take appropriate treatment according to the doctor’s recommendations.
