Key Takeaways
- Arthritis and tendonitis can both cause joint pain, but they affect different structures and respond to different treatments.
- Arthritis involves the joint itself, the cartilage, and the bone, while tendonitis involves the tendons that attach muscle to bone near the joint.
- Symptoms like morning stiffness, swelling, and pain after activity offer important clues, but imaging and a clinical exam are often needed for an accurate diagnosis.
- Treatment ranges from physical therapy and ultrasound-guided injections to advanced therapies designed to identify and treat the specific source of joint pain for longer-lasting relief.
- Grand Rapids Pain is a trusted pain management practice in Grand Rapids, MI, helping patients pinpoint the source of their joint pain and request an appointment to start an effective, individualized treatment plan.
Why Joint Pain Can Be So Confusing
If you have ever woken up with a stiff knee, a sore shoulder, or an achy elbow that gets worse during the day, you have probably wondered the same thing many patients ask: Is this arthritis, or is it something else?
Joint pain is one of the most common reasons people visit a pain specialist, and two of the most frequent culprits, arthritis and tendonitis, can feel surprisingly similar. They are not the same condition, though, and treating one as the other can mean months of frustrating, ineffective care. Understanding the difference is the first step toward getting the right diagnosis and the right plan.
What Is Arthritis?
Arthritis is a broad term for inflammation inside the joint itself. The most common form, osteoarthritis, develops when the cartilage that cushions the ends of your bones gradually wears down. Other forms, like rheumatoid arthritis, involve the immune system attacking the joint lining.
Common arthritis symptoms include:
- Stiffness, especially first thing in the morning or after sitting still.
- A deep, achy pain inside the joint.
- Swelling that comes and goes.
- A grinding or 'bone-on-bone' sensation with movement.
- Reduced range of motion over time.
The Mayo Clinic explains the differences between arthritis types in helpful detail and is a good starting point if you want a deeper overview.
What Is Tendonitis?
Tendonitis is inflammation or irritation of a tendon, the strong, rope-like tissue that connects muscle to bone. It usually develops from repetitive motion, sudden overuse, or strain on a specific tendon, which is why it often shows up around the shoulder, elbow, wrist, hip, knee, or heel.
Common tendonitis symptoms include:
- Pain at a specific spot near the joint, not deep inside it.
- Pain that worsens with the activity that caused it (lifting, throwing, gripping, running).
- Tenderness when you press on the tendon.
- Mild swelling along the tendon.
- Stiffness that often eases with gentle movement.
Arthritis vs. Tendonitis: Side-by-Side
| Feature | Arthritis | Tendonitis |
|---|---|---|
| What is affected | The joint itself (cartilage, bone, joint lining) | A tendon near the joint |
| Typical onset | Gradual, over months or years | Often, after repetitive activity or a specific injury |
| Pain location | Deep, inside the joint | At a specific spot near the joint |
| Stiffness | Worse in the morning or after rest | Often eases with light movement |
| Swelling | In the joint | Along the tendon |
| Common causes | Wear and tear, autoimmune disease, and age | Overuse, repetitive motion, sudden strain |
| Sounds or sensations | Grinding, clicking, 'bone-on-bone.' | Sharp pinch with certain movements |
How to Diagnose the Root Cause of Joint Pain
A correct diagnosis comes from putting several pieces together: your story, a hands-on exam, and the right imaging. The team at Grand Rapids Pain takes a thorough approach because joint pain is rarely caused by a single, obvious thing.
Common diagnostic steps include:
- A detailed history of when the pain started, what it feels like, and what makes it better or worse.
- A physical exam to test the range of motion, strength, and tenderness in specific spots.
- X-rays to evaluate the bones and joint space for signs of arthritis.
- MRI or ultrasound to look at soft tissues, including tendons, ligaments, and the joint lining.
- Diagnostic injections, which can help confirm whether a specific structure is the source of pain.
This level of detail matters. Grand Rapids Pain approaches joint pain at the anatomic level, meaning the team works to identify the specific joint, tendon, nerve, or structure contributing to the pain rather than treating all joint pain the same way. That more precise approach helps patients receive treatments that are matched to the actual source of the problem.
Treatment Options for Arthritis
Treatment for arthritis depends on which joint is affected and how advanced the condition is. Grand Rapids Pain offers a wider range of advanced diagnostic and treatment technologies than many traditional pain clinics, allowing the team to tailor care to the specific cause of each patient’s pain rather than relying on a one-size-fits-all approach.
- Physical therapy and rehab to strengthen the muscles supporting the joint.
- Medication management for inflammation and pain control.
- Ultrasound-guided injections are placed precisely inside the joint.
- Radiofrequency ablation, a minimally invasive treatment that uses heat to interrupt pain signals from irritated joint nerves, can provide longer-lasting relief for some patients.
- Advanced options for joints that have not responded to standard care.
Treatment Options for Tendonitis
Tendonitis usually responds well to conservative care, especially when treatment starts early:
- Activity modification and a clear return-to-activity plan.
- Physical therapy focused on the specific tendon and the muscles around it.
- Ultrasound-guided injections allow the provider to see the tendon in real time and place treatment more precisely at the irritated area, which may improve accuracy and comfort.
- Advanced regenerative or interventional options for stubborn cases.
For chronic tendon problems that have not improved with rest and therapy, the American Academy of Orthopaedic Surgeons offers further reading on tendonitis and related soft-tissue injuries.
Why an Accurate Diagnosis Changes Everything
Patients are often surprised to learn that what they thought was 'just arthritis' was actually tendonitis — or that what looked like a simple tendon strain had an arthritic component underneath. Grand Rapids Pain is one of the few clinics in the region offering a broad range of advanced pain therapies designed to identify and address chronic joint pain at its source. Rather than focusing only on temporary symptom relief, the team works to understand what structure is actually causing the pain and which treatment may provide the most meaningful long-term improvement in comfort, movement, and daily function.

Frequently Asked Questions
How can I tell if my joint pain is arthritis or tendonitis?
Arthritis pain tends to feel deep inside the joint and is worse with morning stiffness, while tendonitis usually causes pain at a specific spot near the joint and gets worse with the activity that caused it. A clinical exam and imaging confirm the diagnosis.
What is the best pain management technique near me for arthritis?
The best technique depends on which joint is affected and how advanced the arthritis is. Options at Grand Rapids Pain range from physical therapy and ultrasound-guided injections to radiofrequency ablation, a treatment that interrupts pain signals from irritated joint nerves and may provide longer-lasting relief for the right candidates.
How do I find a pain specialist near me who treats both arthritis and tendonitis?
Look for a pain management practice that uses advanced imaging and offers a broad range of treatments — not just oral medication. Grand Rapids Pain is a comprehensive pain clinic in Grand Rapids, MI that treats both conditions.
Can tendonitis turn into arthritis?
Tendonitis itself does not become arthritis, but untreated joint problems and altered movement patterns can contribute to wear and tear over time. Addressing tendon issues early helps protect the joint long term.
When should I see a pain specialist for joint pain?
If joint pain has lasted more than a few weeks, is interfering with daily activities, or is not improving with rest, it is time to see a pain specialist. Early diagnosis usually means more treatment options and better long-term outcomes.
