Minor bulging discs do not go away. Once a disc begins to protrude outward, no non-surgical treatment, no matter how minor or severe, will make the herniated disc go away. A herniated disc is a physical structural injury; if the disc protrudes into the annulus fibrosus but has not yet broken through the annulus fibrosus it is called a bulge, if it breaks through the annulus fibrosus and enters the spinal canal it is called a protrusion, and if the disc drops out of the spinal canal it is called a prolapse. Once this injury occurs, it is a permanent change and no non-surgical treatment can restore the herniated disc to its normal structure. Bulging discs are less severe in terms of spinal nerve compression, and most of the symptoms are not serious. Conservative treatments can be chosen, such as rest, avoiding heavy physical labor, wearing a waist immobilization belt, lumbar hot compresses, massages, acupuncture and other physical therapy, and oral anti-inflammatory and analgesic medications for anti-inflammatory and pain relief, such as nimesulide, diclofenac sodium, etc. Oral neurotrophic drugs, such as methylcobalamin, are also available. Oral neurotrophic drugs such as methylcobalamin, adenosylcobalamin. If the symptoms of lumbar intervertebral disc slightly bulging, it is recommended that the patient go to the hospital to improve the examination and formal treatment.
