As a neurosurgeon, I often get asked: “Is running or exercising safe for my spine?”

The answer is—most of the time, yes. In fact, regular movement is one of the best things you can do for your overall spine health. Activities like walking, running, and strength training can help support the muscles that protect your neck and back.

That said, not all exercise is one-size-fits-all. If you’re dealing with ongoing pain, a prior injury, or a spine condition, it’s important to choose the right type and intensity of activity.

Listen to your body. Start gradually. And don’t hesitate to seek guidance if something doesn’t feel right.

Staying active is key—not just for your spine, but for your long-term health.

Neck pain that just won’t go away? Pain, tingling or weakness in your arms or hands? One possible cause is a damaged disc in your neck putting pressure on nearby nerves.

When other treatments don’t bring relief, a procedure called Anterior Cervical Discectomy and Fusion (ACDF) may help.

In simple terms, this surgery removes the problem disc and stabilizes the area to take pressure off the nerves. The goal is to reduce pain, improve movement, and help you get back to your normal routine.

The good news: many patients experience significant relief and a smoother recovery thanks to modern surgical techniques.

If you’ve been struggling with ongoing symptoms, don’t ignore them—there are options available to help you feel better.

While this can be frustrating for patients who thought their problem was resolved, it is a known possibility and one that spine specialists regularly evaluate and treat.

Even after successful surgery, the disc structure remains susceptible to degeneration over time. Factors such as natural aging, physical strain, or residual disc material can contribute to a recurrence.

Common symptoms may include:
• Return of back or neck pain
• Pain radiating into the arm or leg (radiculopathy)
• Numbness, tingling, or weakness

Many patients improve with conservative treatments such as physical therapy and medications, while others may benefit from minimally invasive surgical approaches.
The most important step is accurate diagnosis and individualized treatment planning.

• Numbness, tingling, or weakness in the arms or legs
• Reduced mobility or stiffness

Treatment options vary depending on severity and may include:

Here are a few simple tips to keep your spine healthy this spring:

Warm up before activity – Just like any other muscle group, your back benefits from gentle stretching before lifting or yard work.

Use proper lifting technique – Bend at the knees, keep objects close to your body, and avoid twisting while lifting.

Pace yourself – After a less active winter, jumping into long hours of physical work can strain the spine. Take breaks and build activity gradually.

Strengthen your core – Strong abdominal and back muscles help support the spine and reduce the risk of injury.

Spring is a great time to stay active and prioritize spine health. Taking small preventive steps can go a long way in avoiding neck and back pain.

Persistent back or neck pain isn’t always “just a strain.” In rare cases, it may be discitis — an infection of the intervertebral disc space.

Discitis can occur spontaneously, after a bloodstream infection, or following a spinal procedure. Early diagnosis is critical to prevent complications.

Warning Signs:
• Severe, constant back or neck pain
• Pain that doesn’t improve with rest
• Fever or chills
• Night pain
• Elevated inflammatory markers on blood tests

Sometimes the symptoms are subtle — especially in older adults or patients with weakened immune systems.
