Pain in your lower back. Cramps shooting down your leg. That “pins and needles” feeling. When you have these symptoms, you may assume you have a problem with your spine.
“The problem with assuming is that we often see people who have medical issues that are mistaken as only a spine issue, when it could be a medical issue on its own — or a combination of the two,” says physical medicine/rehab specialist Tagreed Khalaf, MD.
For example, lumbar spinal stenosis is a nerve problem and peripheral arterial disease is related to blood flow, but the two have many symptoms in common. So do spinal stenosis and diabetic neuropathy, or nerve damage in the legs and feet. And disc issues can feel a lot like inflammatory arthritis.
Spinal stenosis is one of the most common causes of spinal pain not related to injury. This narrowing of the space around the spinal cord puts pressure on the nerves. If you have the following symptoms, spinal stenosis may be to blame:
However, Dr. Khalaf notes how common “false positives” are. “Around 21 percent of asymptomatic people over age 60 will show signs of spinal stenosis on an MRI,” she says. “And sometimes spinal stenosis and peripheral arterial disease co-exist. That’s why you need a physical exam, and possibly other tests, to get a clear diagnosis.”
There are a few ways to tell the difference between spinal stenosis and something more serious:
“Serious issues such as malignancies or abdominal aortic aneurysms rarely present spine symptoms,” Dr. Khalaf says, “but sometimes they do. They’re serious enough that ruling them out is important.”
If you do have spinal stenosis, there are ways to find relief:
There’s only one major tip here: See a doctor, whether it is your primary care physician or a specialist. Each condition that mimics spinal problems comes with its own treatments, but the first step is an accurate diagnosis. For example, a nerve test such as electromyography (EMG) can help a doctor spot neuropathy, and a blood-flow test such as the ankle-brachial index (ABI) can distinguish between spinal stenosis and peripheral arterial disease.
“It’s so important to look at all of your symptoms and history and do a thorough examination,” Dr. Khalaf says. “It’s how we can tell the difference between a back issue and a medical condition.”
