Herniated Disc
A herniated disc is one of the most common reasons people see a spine surgeon, and one of the least likely to need surgery. Most herniations settle down within weeks with the right care. The job of a spine surgeon is to tell the difference between the ones that will and the ones that won't.
What a herniated disc is
The discs between the bones of the spine have a tough outer ring and a soft center. When the outer ring weakens or tears, some of the soft center can push outward. If that bulge presses on a nearby nerve root, it produces pain, numbness, or weakness along the path of that nerve: down the arm from the neck, or down the leg from the low back (often called sciatica).
Herniations are most common between the ages of 30 and 55, and they can happen with lifting, twisting, or with no clear event at all. Many people have disc bulges on an MRI that cause no symptoms. A herniation matters when it is pressing on a nerve and the symptoms match.
Symptoms to pay attention to
The hallmark is pain that radiates. A lumbar herniation typically causes buttock, thigh, and calf pain, sometimes into the foot, that is worse with sitting, coughing, or bending forward. A cervical herniation causes pain into the shoulder blade, arm, or hand. Numbness, pins-and-needles, or weakness in a specific muscle group tells the surgeon which nerve is involved.
A few symptoms need urgent attention rather than a scheduled visit: new difficulty controlling the bladder or bowels, numbness in the groin or inner thighs, or rapidly worsening leg weakness. These can indicate cauda equina syndrome, which is a surgical emergency. Go to the emergency department.
How it is diagnosed
The diagnosis starts with the history and a physical examination that tests strength, sensation, and reflexes to locate the nerve involved. An MRI is the best way to see a disc herniation and is ordered when symptoms have lasted more than several weeks, when there is weakness, or when an injection or surgery is being considered. X-rays show alignment and are helpful for planning but do not show discs.
Treatment: nonsurgical first
Most herniated discs improve on their own as the body reabsorbs the herniated material and inflammation around the nerve settles. Reasonable early care includes staying active within comfort rather than bed rest, a short course of anti-inflammatory medication, and physical therapy focused on core strength and nerve mobility. When radiating pain limits daily life or therapy, an epidural steroid injection can calm the nerve enough to let the natural recovery continue.
Dr. Michael's approach is to give nonsurgical care a genuine chance, usually six to twelve weeks, while watching for the signs that surgery would be the better path.
When surgery is the right answer
Surgery is considered when radiating pain remains disabling despite well-conducted nonsurgical care, when there is significant or progressive weakness, or in emergencies. In the low back, the operation is usually a microdiscectomy: a small incision, a microscope or tubular retractor, and removal of only the fragment pressing on the nerve. It is typically an outpatient procedure, and relief of leg pain is often prompt.
In the neck, the two common options are cervical disc replacement, which removes the disc and preserves motion with an artificial disc, and anterior cervical discectomy and fusion (ACDF). Which is appropriate depends on the anatomy, the number of levels involved, and the health of the surrounding joints and bone.
Common questions
Will a herniated disc heal on its own?
Often, yes. A large share of herniations improve substantially within six to twelve weeks as the herniated material shrinks and nerve inflammation settles. The likelihood of needing surgery is lower than most people expect.
Do I need an MRI right away?
Not usually. An MRI is most useful when symptoms have persisted for several weeks, when there is weakness or numbness, or when an injection or surgery is being planned. If you already have imaging, bring it to your visit.
Is a bulging disc the same as a herniated disc?
A bulge is a broad, mild extension of the disc and is extremely common with age, often without symptoms. A herniation is a focal displacement of disc material, and it matters when it is pressing on a nerve and your symptoms match.
What is the recovery after a microdiscectomy?
Most patients go home the same day, walk that day, and return to desk work within one to two weeks. Bending, lifting, and twisting are limited for several weeks while the disc heals. Return to heavier activity is usually around six weeks, guided by how the recovery is going.
