You May Have a Pinched Low Back Nerve Despite What Your Doctor Thinks

POSTED ON IN Back/lumbar Spine BY Chris Centeno

The first day of medical school, our head honcho got up and was brave enough to say that about half of what they would teach us would probably be proven wrong. Yikes, was he ever right. This also applies to what your doctor thinks he or she knows about back pain. For example, we have traditionally been taught that a pinched nerve in the back causes leg symptoms. However, a study published last year changed that. Turns out, if you have pain in the butt area, whether or not you have any leg symptoms, it’s probably a pinched low back nerve.

The Anatomy of the Back: What Is a Pinched Low Back Nerve?

There are a number of conditions that can cause a pinched nerve in the back, but to understand what causes a pinched nerve, let’s first explore the anatomy of the back. The foundation of the spinal column consists of 24 vertebrae, or backbones stacked one on top of the other with a disc in between each level at the front. The disc absorbs shock and provides cushioning for the vertebrae. In the back part of the spine, each vertebra comes together with the next at the facet joint, and these facet joints run the length of the spinal column. The spinal cord is the large bundle of nerves that is housed inside the canal, which is surrounded and protected by the spinal column. These nerves transmit feeling throughout our body.

The low back nerves can become pinched with foraminal stenosis, or a narrowing of the foramen, the tunnels along the spinal column that the nerves travel through. Bulging or herniated discs and arthritis in the joints of the spine can also cause pinched nerves.

The New Study

The purpose of the new study was to explore how pain is distributed in patients who have chronic disorders of the low back. There were over 1,800 subjects with chronic low back pain in the study, and these patients were between 20 and 79 years of age. They were first screened via questionnaire to score their pain and pinpoint the precise location of the pain, which included the low back, butt, and legs. Then they were given a validated questionnaire that can identify whether nerve pain is the main issue. The authors concluded that even if the patient didn’t have leg symptoms, most of the patients with butt area pain likely had nerve issues in the low back. This is opposite what your doctor has been taught, who may still believe that you need to have leg symptom for him or her to take a look at pinched nerves.

Why is this an important study? Many patients with chronic back conditions have pain in their butt. Now that we know that just like symptoms in the leg this can relate back to a pinched low back nerve, doctors can now look at the low back MRI just a bit differently. For example, there have likely been millions of patients through the years with a clear pinched nerve on their low back MRI with butt pain and without leg symptoms who have been told that their MRI doesn’t explain their symptoms!

The upshot? If you have back pain that goes into your butt area, you may well have a pinched nerve in your back. Your doctor may not agree if you don’t have leg symptoms; however, based on this new research, your doctor may need an educational update!

    JEAN BURKE says

    My back pain just started one day no previous signs at all. My pain is across my middle back and radiated to under my breasts. This has been going on for 2 months. I have had a chest X-Ray, A CT Scan of my abdomen, An Ultra-Sound of my Kidney's, Liver, Pancreas, and Gallbladder. They didn't find anything. On May 18 I will be going to a Dr. that does Interventional Spine and Sports Medicine, Also Physical Medicine & Rehabilitation. Maybe he will fine out what it is.

    It takes about a hour to do the type of exam needed to diagnose a problem. You can find out with a phone call if this doctor spends that kind of time with his patients. Please see:


    Gregory Meister says

    Ok but what do you do if you have the pinched nerve in the back that is causung pain in lower back and butt


    Chris Centeno says

    First, get the type of exam that can pinpoint the cause of the problem and treat the issue with precise image guided injections of your own platelet or stem cells. Please see: As you scroll down on that page you'll also find an On-Demand Spine Webinar, and a video of an actual disc procedure. If you'd like to see if you'd be a Candidate for a procedure, please submit the Candidate form.
