The Causes of Joint Pain | Yashar Neurosurgery - Blog

Joint pain can come from arthritis, inflammation, overuse, or even nerve compression from the spine, and a clear diagnosis helps you choose the right treatment—often without surgery.

TABLE OF CONTENTS

Joint pain rarely announces itself with a clear label. It often starts as a knee that aches after stairs, fingers that feel stiff when you wake up, or a hip that makes you hesitate before standing. When that discomfort becomes predictable—or starts changing how you work, exercise, sleep, or drive—the most helpful next step is figuring out what structure is actually generating the pain. “Joint pain” is a symptom, not a diagnosis, and the right treatment depends on the cause.

Many patients who come to Yashar Neurosurgery are surprised to learn that some “joint” symptoms (especially pain that travels, tingling, or weakness) can involve irritated nerves from the spine. If you’re looking for answers—and want care that keeps conservative options on the table while also offering advanced procedures when needed—this guide breaks down the most common reasons joints hurt, what bone spurs really are, and when a spine evaluation makes sense.

What Joint Pain Can Mean (and Why It’s Not Always the Joint)

A joint is where two bones meet, supported by cartilage, ligaments, tendons, and a thin lining (synovium) that helps the joint move smoothly. Pain can come from any of these tissues, and different causes can feel similar at first: aching, sharp pain, swelling, stiffness, or a “catching” sensation.

It also helps to know that pain can be “referred.” A pinched or inflamed nerve in the neck or low back can create symptoms that show up far away from the spine—into a shoulder, arm, hand, hip, buttock, or leg. That’s one reason a focused history and exam matter as much as imaging.

Common Causes of Joint Pain

Some joint pain is short-lived (for example, a minor strain or an overuse flare after a new workout). Other causes are progressive and benefit from early diagnosis. Common categories include wear-and-tear arthritis, inflammatory arthritis, tendon or bursa irritation, crystal arthritis, and systemic illness.

  • Osteoarthritis (degenerative “wear-and-tear” arthritis)
  • Inflammatory arthritis (such as rheumatoid arthritis)
  • Bursitis (inflamed fluid-filled sac near a joint)
  • Tendinitis (irritation of a tendon)
  • Gout (crystal-related arthritis, often sudden and intense)
  • Fibromyalgia (widespread pain and tenderness)
  • Overuse and flare-ups of old injuries
  • Certain infections or systemic illnesses that can cause temporary joint aches

If you are over about 40 and your symptoms are becoming more consistent—especially stiffness and pain with activity—osteoarthritis is one of the most common underlying explanations.

Osteoarthritis: the Most Common Driver of Persistent Joint Pain

Osteoarthritis happens when cartilage—the smooth, protective layer on the ends of bones—gradually wears down. Healthy cartilage helps bones glide without friction and absorbs impact. As cartilage thins, the joint becomes more irritated with movement, and inflammation can follow.

Osteoarthritis commonly affects the hands, wrists, hips, knees, and the spine. Many patients describe a recognizable pattern:

  • Stiffness after rest (often in the morning or after sitting)
  • Aching that increases with activity and eases with short rest
  • Swelling or tenderness around the joint
  • Grinding, clicking, or reduced range of motion

Over time, arthritic joints can develop extra bony growth at the edges. That’s where bone spurs come in.

What Is a Bone Spur (and When Does It Cause Symptoms)?

A bone spur, also called an osteophyte, is an extra bony growth that often forms as the body responds to joint degeneration or long-term mechanical stress. Bone spurs are common, and many people have them on imaging without feeling any symptoms.

Symptoms are more likely when a spur starts to:

  • Limit joint motion by crowding the joint space
  • Irritate nearby soft tissues, contributing to inflammation and pain
  • Press on a nerve, especially when bone spurs develop in the spine

When nerves are involved, the sensation may shift from “sore joint” to nerve-type symptoms like burning pain, tingling, numbness, cramping, or weakness. Bone spurs can also contribute to narrowing around nerves in the neck or low back.

Signs Your “Joint Pain” May Be Coming from the Spine

Some clues point away from a single joint problem and toward nerve irritation in the neck or back. This doesn’t mean the joint is “fine”—it means the pain generator may be higher up the chain.

Consider a spine evaluation if you notice:

  • Pain that radiates down an arm or leg rather than staying in one joint
  • Numbness or tingling in the hand, fingers, foot, or toes
  • Weakness (grip strength, lifting the foot, or pushing off when walking)
  • Symptoms that worsen with standing or walking and improve with sitting or leaning forward
  • Balance changes or clumsiness in the hands

One common cause of nerve symptoms is spinal stenosis (narrowing around the nerves or spinal cord). Degenerative changes, including disc wear, can also contribute; see degenerative disc disease treatment for an overview.

How Joint Pain and Bone Spurs Are Diagnosed

A strong diagnosis starts with your timeline and triggers: what movements bring symptoms on, what relieves them, whether swelling is present, and whether pain stays local or travels. A physical exam can assess range of motion, tenderness, swelling, gait, strength, reflexes, and sensation—often clarifying whether pain is more likely joint-based, tendon-based, or nerve-based.

Imaging may be recommended depending on the suspected cause:

  • X-rays to assess arthritis changes, joint space narrowing, alignment, and many bone spurs
  • MRI to evaluate cartilage, soft tissues, discs, and nerve compression
  • CT for more detailed bony anatomy in selected cases

The goal is not just to “find something” on a scan—many people have imaging changes without symptoms—but to match your exam and symptoms to the structure most likely causing your pain.

Treatment Options: from Conservative Care to Surgical Relief

Many causes of joint pain improve without surgery. The best plan is targeted: calming inflammation, improving mechanics, and protecting function so you can keep moving.

Non-Surgical Treatments

  • Physical therapy to strengthen supporting muscles and improve movement patterns
  • Anti-inflammatory medications when appropriate, guided by your medical history
  • Injections (such as corticosteroid injections) for selected inflammatory or arthritic pain patterns
  • Activity modification that reduces flare-ups without unnecessary inactivity

If symptoms are being driven by nerve compression, treatment may focus on relieving pressure on the nerve. In some patients, procedures categorized as spinal decompression can create more room for nerves and reduce radiating pain or numbness.

When Surgery May Be Considered

Surgery is usually discussed when pain remains persistent despite appropriate conservative care, when function is significantly limited, or when there are progressive neurologic findings (such as worsening weakness). Bone spurs along the spine require particular care because the spinal cord and nerve roots are delicate structures.

When indicated, minimally invasive spine surgery may be an option to relieve nerve compression while minimizing disruption to surrounding muscle and soft tissue. The specific approach depends on the location of the spur, the degree of narrowing, and whether there are additional issues such as disc degeneration or instability.

Finding the Best Minimally Invasive Spine Surgeon in Los Angeles for Nerve-Related Joint Pain

If your joint pain is starting to behave like nerve pain—radiating symptoms, numbness, tingling, weakness, or walking limitation—an evaluation with a spine specialist can help identify whether the source is in the joint, the spine, or both. At Yashar Neurosurgery, Parham Yashar, MD focuses on clear diagnosis, patient education, and a full spectrum of options, from conservative care through advanced procedures when appropriate.

To discuss your symptoms and learn whether a spine-based cause like bone spurs or stenosis may be contributing, you can request a consultation with Yashar Neurosurgery in Los Angeles at (424) 209-2669 or explore our spine surgery resources before your visit.
