A 4-5 disc bulge is generally not very serious. A 4-5 bulging disc refers to a bulging disc in the lumbar spine between the fourth and fifth vertebrae, which is the early stage of lumbar disc herniation and is relatively not serious, and generally does not require special intervention if there are no clinical symptoms. If there are clinical symptoms, they are relatively mild, such as mild lumbar pain, limitation of lumbar spine activities, and radiating pain in the lower limbs, etc., which generally do not affect daily life and rest. Appropriate exercises for the lumbar and back muscles in daily life can improve the clinical symptoms, and early and active cooperation with the doctor’s treatment to avoid adverse effects. Patients with 4-5 bulging discs are advised to receive treatment as early as possible under the guidance of a doctor to avoid aggravation of the condition and increase the difficulty of treatment.
