Depending on the severity of lumbar 5 and sacral 1 disc mild posterior protrusion can be treated with general treatment, physical therapy and surgery. 1. General treatment: If the patient’s lumbar 5 and sacral 1 intervertebral disc mild posterior protrusion is not accompanied by obvious clinical manifestations, he/she can change his/her life style, reduce the weight of lumbar vertebrae, and also rest with braking to limit the activities of lumbar region, and if he/she has slight pain, he/she can take drugs such as ibuprofen for anti-inflammatory and analgesic treatment. 2. Physical therapy: If the patient’s lumbar 5 and sacral 1 intervertebral discs are mildly protruding with pain, lumbar traction can be carried out to alleviate the pain, and red light therapy and appropriate hot compresses can be used to promote blood circulation and alleviate local pain. 3. Surgery: If the lumbar 5 and sacral 1 intervertebral discs have mild posterior herniation with severe discomfort that is not relieved by conservative treatments, surgery can be performed to remove the nucleus pulposus or excise the herniated portion of the disc, if necessary. Mild posterior herniation of lumbar 5 and sacral 1 intervertebral discs should be combined with the clinical manifestations, and the doctor should choose the appropriate treatment, pay attention to the lumbar protection in general, avoid standing for a long time, sitting for a long time, and follow the doctor’s instructions on the use of medication.
