Just as it sounds, spinal stenosis is a condition that affects our spine by narrowing the spinal columns and compressing the spinal cord. It’s also sometimes referred to as pseudo-claudication, central spinal stenosis, or foraminal spinal stenosis.
This condition isn’t often heard or talked about, so you likely don’t know much about it! If that’s the case, then continue reading to find out more about spinal stenosis and the common symptoms, causes, how it is diagnosed and the possible forms of treatment…
1. What Is It?
Our spine is like the pillar of support to our posture and stability. It consists of a column of bones that run up our back that are referred to as vertebrae. It is what allows us to sit up straight, twist and turn.
The spine is very delicate because it is made up of nerve that run through the vertebrae, conducting signals to the brain and the rest of the body. “The surrounding bone and tissues protect these nerves. If they’re damaged or impaired in any way, it can affect functions like walking, balance, and sensation,” writes Healthline.
According to WebMD, spinal stenosis typically occurs due to arthritis which causes the spinal column to narrow and compress the spinal cord. Healthline explains that the process is usually gradual, it can occur anywhere along the spine, and if the narrowing is extensive it can compress the nerves and cause a slew of other symptoms.
2. Types of Spinal Stenosis
There are two different types of spinal stenosis: cervical stenosis and lumbar stenosis. These two types are differentiated by where they occur on the spine, and according to the Mayo Clinic, it’s possibly to have more than one type.
Cervical stenosis is when the narrowing of the spine occurs in the neck, while lumbar occurs in the lower back. Lumbar stenosis is the most common form of spinal stenosis.
3. Symptoms of Spinal Stenosis: Cervical
The Mayo Clinic explains that the symptoms caused by spinal stenosis depend on its severity. If the narrowing is minimal, then there will be evidence of the condition on an MRI or CT scan, but other than that there might not be any symptoms. In other cases, the symptoms will come on gradually and slowly and differ depending on location and what nerves are affected.
When it comes to cervical spinal stenosis, there is often numbness, tingling or weakness in a hand, arms, foot or leg, says the source. A person might also have problems with walking due to issues with balance. Since it is located in the neck it will often cause neck pain. In addition to all this, in severe cases it can cause bowel or bladder dysfunction in the form of urinary urgency or incontinence.
4. Symptoms of Spinal Stenosis: Lumbar
As previously mentioned, lumbar stenosis occurs in the lower back. The symptoms associated with this type of spinal stenosis include numbness or tingling in the leg or foot. A person could also experience weakness in their legs or feet, as well as “pain or cramping in one or both legs when you stand for long periods of time or when you walk, which usually eases when you bend forward or sit,” writes the Mayo Clinic. And not surprisingly, lumbar spinal stenosis often causes back pain.
Healthline points out that people with spinal stenosis can often find relief when they sit down, but the pain will just return once they begin walking and standing again.
5. Causes of Spinal Stenosis
Spinal stenosis can be caused by a number of different things. Two of the most common causes are aging and arthritis. According to WebMD, arthritis occurs when there is a breakdown of cartilage, “the cushiony material between your bones,” and the growth of bones. Healthline expands by writing that as our body ages, it goes through some deenerative processes, “tissues in your spine may start to thicken, and bones may get bigger, compressing your nerves.”
Age can also cause conditions like osteoarthritis and rheumatoid arthritis, both of which cause inflammation that can contribute to spinal stenosis. “Osteoarthritis can lead to disc changes, a thickening of the ligaments of the spine and bone spurs,” writes WebMD. This can also put pressure on the spinal cord and nerves.
6. Conditions That Can Cause Stenosis
In addition to aging and arthritis, there are other conditions that can cause stenosis including, “spine defects at birth, a naturally narrow spinal cord, spinal curvature, or scoliosis, Paget’s disease of the bone, which causes abnormal bone destruction and regrowth, bone tumors,” as well as achondroplasia, which is a form of dwarfism, writes Healthline.
WebMD also lists some other potential causes including any injury that might have caused a fracture or inflammation of the spine, or a herniated disc, which occurs when the cushions are cracked and material seeps into the spinal cord and nerves.
7. Risk Factors
There are certain factors that can increase a person’s risk for developing spinal stenosis. As we previously mentioned, the two main causes of spinal stenosis are age and arthritis. As a result, people over the age of 50 are at a higher risk.
The Mayo Clinic notes that spinal stenosis can occur in younger people due to degenerative changes, but other conditions can also increase a persons risk like “trauma, congenital spinal deformity such as scoliosis, and a genetic disease affecting bone and muscle development throughout the body.”
8. How is it Diagnosed?
We previously mentioned that in some cases spinal stenosis will not cause any symptoms, but it will appear on an MRI or CT scan. In order to diagnose this condition, a doctor will ask a few questions about your medical history and order either an X-ray, magnetic resonance imaging (MRI), or computerized tomography (CT scan), explains WebMD.
9. Treatment for Stenosis
There are several different forms of treatment available for people with spinal stenosis. WebMD lists medication as the first option. Since back and neck pain are two of the common symptoms, a patient could turn to pain remedies like aspirin, acetaminophen (Tylenol), ibuprofen (Advil, Motrin, and naproxen for short-term relief. Other medications that might be prescribed by a doctor include muscle relaxants or anti-seizure medications to relieve muscle spasms and damaged nerves.
The next treatment option that WebMD lists is corticosteroid injection. “Your doctor will inject a steroid such as prednisone into your back or neck,” writes the source. “Steroids make inflammation go down. However, because of side effects, they are used sparingly.”
The other options are anesthetics, exercise, assistive devices like braces, corset, or a walker. In severe cases, surgery might be a viable option. This is only for people who have difficulty walking, or issues with their bladder and bowels, says WebMD. There are risks associated with surgery, so you need to talk to your doctor to find out what would work best for you.
10. What You Can Do at Home
There are a number of things that can be done at home to help relieve the symptoms of spinal stenosis. One of the best things to do is exercise, says WebMD. It doesn’t have to be strenuous or time consuming. Just 30-minutes of walking every other day (we’ll get into more details on this in the next slide).
You can also use a hot or cold compress. Heat helps loosen up the muscles, writes the source, while cold reduces inflammation. You can use this compress on either the neck or lower back, depending on where the stenosis is located. If you don’t have a compress, try taking a hot shower.
WebMD also lists practicing good posture by standing up straight, sitting in a supportive chair, or sleeping on a firm mattress. When lifting heavy objects, always bend from the knees and do not put any strain on your back.
11. Exercises for Spinal Stenosis
Even though spinal stenosis causes back pain and sometimes difficulty moving, Healthline explains that exercise and movement in general, are crucial to overall health. It can improve flexibility, balance, and enable a person to move better, says the source. People with stenosis should start stretching every day, several times a day.
If you were someone who didn’t exercise prior to developing this condition, it’s important that you start, but take it slow. Begin with only a few minutes a day and work your way up to 30 minutes, three times a week. If exercise continues to be too painful, Healthline recommends taking the exercise routine into the pool. “The buoyancy of the water makes it easier to move and get full range of motion,” writes the source.
To learn about the specific exercises and stretches that can help strengthen your back and abdominal muscles, you should consult with your doctor or physical therapist. In severe cases a back brace might be needed for extra support.
12. Long Term Outlook
While spinal stenosis is serious and can have a huge impact on a person’s life, many people with this condition live very full and active lives. The biggest thing is that they will have to make modifications when it comes to physical activity and some might continue to struggle with pain following treatment or surgery, writes Healthline.
