What is tiny central protrusion in c4-5?

A tiny central protrusion at the C4-5 level refers to a mild bulging of the intervertebral disc in the cervical spine, specifically between the fourth and fifth cervical vertebrae. This protrusion may impinge on nearby spinal structures, potentially causing symptoms such as neck pain, tingling, or weakness in the arms if it affects nerve roots. It is often identified through imaging studies like MRI and may require monitoring or conservative treatment, depending on the severity of symptoms.
