Cervical Disc Herniation

Between every two vertebrae in your neck sits a small cushioning disc — a tough fibrous ring on the outside (the annulus fibrosus) wrapped around a gel-like center (the nucleus pulposus). A cervical disc herniation happens when that gel pushes through a tear in the outer ring and presses on something it shouldn't — usually a nerve root as it exits the spine, sometimes the spinal cord itself. The two discs in the lower neck (between vertebrae C5–C6 and C6–C7) get hit most often because they bear the most motion.

Sudden "soft" herniations usually happen to people under 50 — sometimes from one specific event (heavy lifting, a sharp twist), sometimes building up gradually as the disc dries out with age. The good news: most resolve with non-surgical care, often within weeks.

A cervical disc herniation usually announces itself with sharp pain that starts in the neck and shoots down one arm along a predictable path — which arm and which fingers depend on which disc has herniated. A C5–C6 disc (the most common) sends pain and numbness into your thumb and index finger; a C6–C7 disc targets the middle finger. Turning your head toward the painful side or looking up often intensifies the pain, because those motions close down the space around the nerve even further.

Along with pain you may notice tingling or a "dead" feeling in the affected fingers, and sometimes weakness in a specific motion — difficulty gripping with a C6 nerve, trouble straightening your elbow with a C7 nerve. Neck stiffness, a deep ache between your shoulder blade and your spine, and muscle spasm along the side of your neck are common companions. Most episodes peak in the first week or two and then steadily improve as the swelling around the nerve settles.

Your symptoms and your exam tell your surgeon which level is likely to blame — pain that radiates down a particular arm, weakness in a specific muscle, numbness in a specific finger pattern. MRI is the imaging test that confirms it: it shows the disc, exactly where it's pressing, and whether the spinal cord itself is being squeezed. EMG and nerve conduction studies are added when more than one level looks involved or when the picture isn't clear-cut.

Surgery helps only a small minority of spine patients — usually those with a specific structural problem plus a nerve issue that isn’t getting better with a structured non-operative trial. When that step is genuinely warranted, OSI coordinates it the same way we coordinate every other part of your care: imaging, records, and the handoff are handled for you, so no part of the process falls on your shoulders.

Emergency. Sudden loss of hand dexterity, worsening balance, arm or leg weakness, or loss of bladder or bowel control can reflect spinal-cord compression — go to the nearest emergency department rather than waiting for a clinic appointment.
