Lumbar Disc Herniation Size: Surgery Considerations
Lumbar Disc Herniation, Disc Size, and Non-Surgical Treatment Options in Shelton, CT
Lumbar disc herniation can make everyday activities surprisingly difficult. Simple things like walking, standing at the sink, sitting at your desk, or getting in and out of the car may suddenly feel painful or exhausting.
Many patients notice their sleep is disturbed, lifting becomes stressful, exercise routines are interrupted, and family activities are no longer enjoyable because they are worried about triggering a flare-up of back or leg pain (often called sciatica-type pain).
At Connecticut Disc and Laser Therapy Centers in Shelton, CT, we evaluate patients dealing with lumbar disc herniation, sciatica-type leg pain, chronic low back pain, nerve irritation, and related spine conditions that affect daily life and mobility.
The good news?
A lumbar disc herniation does not automatically mean you need surgery, spinal injections, or long-term pain medication. For the right patient, advanced non-surgical treatment options may help reduce pain, improve mobility, calm irritated tissues, and support better function as part of a comprehensive care plan.

1. What Is a Lumbar Disc Herniation?
The lumbar spine refers to the lower part of your back. Between each pair of vertebrae (spinal bones) sits a disc that acts like a cushion or shock absorber. These discs help you bend, twist, and move comfortably.
A lumbar disc herniation happens when part of the soft inner material of the disc pushes out through a tear or weakness in the tougher outer layer. This disc material can irritate nearby nerves or the spinal canal and may lead to pain, numbness, tingling, or weakness, often traveling down into the leg or foot (commonly called sciatica-type symptoms).
2. Common Symptoms and How Daily Life Is Affected
Not everyone with a lumbar disc herniation has the same symptoms. Some people feel mostly low back pain, while others feel more leg pain, numbness, or tingling. Some notice weakness when trying to lift the foot or stand on their toes or heels.
Pain with sitting longer than a few minutes (especially in the car or at work)
Difficulty standing in one place, such as while cooking or doing dishes
Increased pain with bending, lifting, or twisting (laundry, yardwork, childcare)
Trouble finding a comfortable sleeping position or frequent waking due to pain
Hesitation with exercise, walking, or recreational activities due to fear of flare-ups
These limitations can affect work, hobbies, family time, and overall quality of life. That is why many patients are understandably worried when they hear “disc herniation” and immediately think “surgery.”
3. Does a Bigger Disc Herniation Automatically Mean Surgery?
It is easy to assume that the larger the disc herniation, the more pressure it puts on the nerves, and the more likely surgery becomes. However, research has shown that this is not always the case. In fact, disc size on MRI does not reliably predict who will and will not need surgery after a period of non-surgical care.
Standard treatment guidelines for lumbar disc herniation usually recommend starting with non-surgical care for at least six weeks, unless a serious “red flag” condition is present. Red flags can include things like severe infection, unstable fracture, certain cancers, or cauda equina syndrome (a rare but serious condition that can affect bowel and bladder function). Fortunately, these situations are not common, but they do require urgent medical attention and are handled differently than typical disc-related back or leg pain.
Note: If you experience sudden loss of bowel or bladder control, severe weakness in both legs, or numbness in the area around the groin (“saddle anesthesia”), seek emergency medical care right away.
4. What Research Says About Disc Size and the Need for Surgery
A study of 368 patients with lumbar disc herniation who received at least six weeks of non-surgical care found that about 91% did not go on to have surgery within the following year. Only around 9% ended up needing an operation during that time period, even though all of them started with disc herniation on imaging and symptoms significant enough to seek care.
When researchers compared the MRI scans of the patients who did have surgery to those who did not, they looked at how much of the spinal canal was occupied or “blocked” by the herniated disc. Surprisingly, there was essentially no difference between the two groups in terms of the percentage of the canal taken up by the disc material. In other words, disc size alone did not explain who needed surgery and who improved with conservative care.
This research suggests that the percentage of the spinal canal narrowed by the herniation does not reliably predict which patients will fail non-surgical care and require surgery.
This is important because some spine surgeons and patients still focus heavily on the size of the herniation when making decisions. While MRI findings matter, they are only one piece of the puzzle. Symptoms, exam findings, response to care, and overall health all play key roles in deciding the best treatment path for each individual.
5. Who May Not Respond as Well to Surgery?
Even when surgery is chosen, not every patient has the same outcome. A 2019 study reviewed 556 patients over a three-year period and looked at factors that might be linked with less favorable results after lumbar disc surgery. One key finding was that patients who continued to have moderate to severe leg pain early after surgery tended to have higher disability scores over time.
This group was also more likely to have a history of smoking and chronic back pain. Smoking is known to affect circulation and healing, and many surgeons prefer to avoid operating on smokers when possible because of higher risks of complications and slower recovery. Long-standing back pain may also suggest that more than one factor is contributing to the symptoms, not just the disc herniation itself.
When considering any procedure, it is important to look at the whole person—overall health, lifestyle factors, and other spinal changes—not just the MRI report.
6. Why MRI Findings Alone Are Not the Final Answer
MRI is a powerful tool, but it has limits. Many people with no pain at all have disc bulges or even herniations on MRI. Others have significant pain with relatively small changes on imaging. That is why a careful, in-person evaluation is so important when deciding on treatment options for lumbar disc herniation.
MRI shows structure, not how you move or function day to day
Symptoms may improve even if the MRI looks similar over time
Some disc herniations can shrink or change shape naturally as the body adapts
At Connecticut Disc and Laser Therapy Centers, imaging is considered alongside a detailed history, physical examination, and your goals for activity, work, and lifestyle. This helps create a more complete picture and may open the door to non-surgical options that fit your situation.
7. Advanced Non-Surgical Options for Lumbar Disc Herniation
For many patients, guidelines support a trial of non-surgical care before considering surgery. This may include a combination of gentle spinal care, specific exercises, lifestyle modifications, and advanced technologies designed to support disc and nerve health. Individual results vary, and a proper evaluation is necessary to determine whether any treatment is appropriate for your condition.
At our office, we focus on advanced non-surgical options that may help reduce pain, improve mobility, and calm irritated tissues for the right patient. These may include specialized disc-focused therapies, laser therapy, and movement-based care, used together as part of a personalized treatment plan when appropriate.
8. How Spinal Decompression Therapy May Help Support Disc and Nerve Health
Spinal decompression therapy is a non-surgical treatment that gently stretches the spine in a controlled manner. For the right patient, this type of therapy may help reduce pressure within the disc and on nearby nerves, promote improved circulation to the area, and support the body’s natural healing processes over time.
During a spinal decompression session, you remain comfortably positioned while a specialized table applies carefully measured traction to the spine. The goal is not to “snap” anything into place, but to create gentle, repeated cycles of decompression and relaxation that may help relieve pressure on irritated nerve roots associated with lumbar disc herniation for appropriate candidates.

9. MLS Laser Therapy and emField Pro High Energy Inductive Therapy
In addition to decompression, some patients may benefit from therapies designed to help calm irritated tissues and support healthy circulation in the area of the disc and surrounding muscles. At our Shelton office, this may include MLS laser therapy and emField Pro high energy inductive therapy when appropriate for the individual patient.
MLS Laser Therapy
MLS laser therapy uses specific wavelengths of light delivered to targeted tissues. For the right patient, this may help support circulation, reduce local inflammation, and promote a healing environment in the soft tissues surrounding the lumbar spine. Treatments are non-invasive and typically well-tolerated, with sessions lasting only a short period of time.
You can read more on our MLS Laser Therapy page.
emField Pro High Energy Inductive Therapy
emField Pro high energy inductive therapy uses pulsed electromagnetic fields delivered to targeted regions of the body. When appropriate, this technology may help relax tight muscles, support local circulation, and assist with neuromuscular re-education as part of a broader treatment plan for lumbar disc-related pain and dysfunction.

10. Chiropractic and Movement-Based Care for Lumbar Disc Herniation
Many treatment guidelines support chiropractic and movement-based care as non-surgical options for lumbar disc herniation. This may include gentle spinal adjustments or mobilization, specific exercises to support core strength and stability, and strategies to improve posture and body mechanics during daily activities such as sitting, driving, lifting, and working.
For appropriate patients, these approaches may help reduce mechanical stress on the disc and surrounding joints, improve mobility, and support healthier movement patterns over time. They are often combined with other therapies, such as decompression or laser, as part of a comprehensive non-surgical plan tailored to the individual.

11. When Is Surgical Consultation Considered?
While the majority of lumbar disc herniation patients may improve without surgery, there are times when a surgical consultation is appropriate. This may include situations where:
Severe or progressive weakness is present in the leg or foot
Symptoms do not improve after a reasonable course of appropriate non-surgical care
Red flag signs suggest a more serious underlying condition
Our role at Connecticut Disc and Laser Therapy Centers is to carefully evaluate your condition, provide advanced non-surgical options when appropriate, and refer for additional medical or surgical opinions if your findings suggest that is in your best interest. The goal is to help you make informed decisions based on your symptoms, exam, imaging, and overall health—not just the size of the disc herniation on MRI.
12. Why Patients in Shelton Choose Connecticut Disc and Laser Therapy Centers

14. Bottom Line
A lumbar disc herniation can be painful and disruptive, but the size of the herniation on MRI does not automatically determine your future. Many patients improve with appropriate non-surgical care, and research suggests that only a minority go on to need surgery after a trial of conservative treatment—especially when no red flag signs are present.
At Connecticut Disc and Laser Therapy Centers in Shelton, CT, we focus on advanced, non-surgical options that may help the right patient reduce pain, improve mobility, and support better function. A careful evaluation is the first step in determining whether therapies such as spinal decompression, MLS laser therapy, emField Pro high energy inductive therapy, and chiropractic or movement-based care are appropriate for your specific condition.
If you are living with back or leg pain related to a lumbar disc herniation, you do not have to make decisions based on MRI images alone. A personalized, non-surgical approach may provide meaningful support for the right patient as part of a comprehensive plan.
