Introduction
Lumbar disc protrusion is a type of lumbar disc herniation in which the nucleus pulposus breaches only the inner annulus fibrosus layer but has not yet penetrated the outer annulus fibrosus layer; in some cases, it may cause partial bulging that compresses a nerve root. Symptoms of nerve compression are typically mild or absent—patients may experience only low back pain or mild numbness in the lower limbs, but these symptoms are generally not severe. Adequate rest, avoidance of strenuous physical labor, and appropriate exercise are usually sufficient for management.

Individuals who sit for prolonged periods place considerable stress on the lumbar spine, which—when severe—can lead to various lumbar disorders. Today, many people suffer from conditions such as lumbar disc herniation. To achieve optimal treatment, it is essential first to understand its underlying causes. So, how serious is an L4-L5 disc bulge?

How serious is an L4-L5 disc bulge?

Lumbar disc bulge is a milder form of lumbar disc herniation, characterized by the nucleus pulposus protruding through only the inner layer of the annulus fibrosus—but not yet breaching the outer fibrous ring. In some cases, the bulging disc may partially compress adjacent nerve roots. Typically, neurological symptoms are mild or absent; patients may experience only low back pain or mild numbness in the lower limbs, and the condition is generally not considered severe.

For patients with this condition, adequate rest, avoidance of strenuous physical labor, and appropriate therapeutic exercise often yield favorable recovery outcomes. Lumbar disc bulge is typically not severe; however, treatment at a reputable hospital is recommended to prevent disease progression.

An intervertebral disc consists of three components: the nucleus pulposus, the annulus fibrosus, and cartilaginous endplates. A disc herniation—or bulge—occurs when the nucleus pulposus and/or portions of the annulus fibrosus protrude outward, compressing the spinal cord or corresponding nerve roots. In contrast, a disc bulge refers specifically to circumferential expansion of the annulus fibrosus without significant compression of the neural foramina or adjacent neural structures. Modern acupuncture therapy is recommended for treatment. “Jingu Tong” (Ancient-Modern Integration) offers proprietary pain-relieving patches and a unique modern acupuncture approach integrating moxibustion, thermotherapy, and magnetic therapy. This triple-action modality not only helps suppress the progression and deterioration of osteoarticular diseases but also reduces recurrence after patient recovery.
