Last week, my friend Jenna messaged me in frustration: "I can't even open a jar without pain near my thumb!" She'd tried pain patches, herbal creams, and endless wrist rests—but nothing worked.

Turns out, she wasn't dealing with arthritis at all. What she had was tendon inflammation, not a joint problem. And that single detail completely changed how she needed to treat it.

Dr. Samuel Grant, an orthopedic specialist at Westfield Medical Center, explains, "The wrist is a complex structure of bones, tendons, and cartilage. Treating tendon inflammation the same way you'd treat arthritis is like fixing a sprained ankle with dental floss—it simply doesn't work."

2. Know Whether It's Tendonitis or Joint Strain—They Need Different Treatments

De Quervain's and arthritis aren't twins—they demand opposite care. The tricky part is that both can cause pain in the same general area: the base of your thumb near your wrist. But their causes and treatments are completely different.

Example 1: If pain shoots through your thumb when twisting a jar lid, gripping chopsticks, or steering a wheel, you may have De Quervain's tenosynovitis. This condition happens when the sheath around your thumb tendons becomes inflamed, often from overuse or repetitive movements like typing or scrolling. The best remedy isn't stronger painkillers—it's rest and stabilization. Use a thumb splint, avoid repetitive pinching, and apply cold compresses twice a day to calm inflammation.

Example 2: But if the pain feels deeper inside your wrist and you notice a "click" or dull ache when turning or bending it, you might be facing a TFCC (triangular fibrocartilage complex) injury. This affects the cartilage cushion on the pinky side of your wrist. Unlike tendonitis, TFCC injuries are worsened by poor wrist alignment or over-twisting. Treatment focuses on load adjustment—avoiding heavy lifting, strengthening the forearm muscles, and learning proper wrist posture during daily tasks.

Example 3: If your wrist feels stiff or swollen after long inactivity—like sleeping or typing for hours—you may have early degenerative joint changes. These require gentle movement, warm compresses, and sometimes physical therapy, not full immobilization. Freezing the joint for too long only makes stiffness worse.

3. Three Simple Tests to Help You Guess What's Going On

You don't need fancy scans to get a rough idea of what's happening—simple self-checks can guide your next step.

1. The jar test: Try twisting open a jar lid. If sharp pain hits the thumb side of your wrist, it's likely De Quervain's.

2. The ulnar press test: Press the pinky side of your wrist gently while rotating your hand. If that causes a dull, deep ache or clicking, you might have a TFCC strain.

3. The morning stiffness check: If your wrist feels tight but loosens up after a few minutes of movement, it may be joint-related, not tendon-based.

Of course, these aren't replacements for diagnosis—but they help you describe symptoms clearly when seeing a doctor.

4. Treat Each Condition the Right Way

For tendon inflammation (De Quervain's):

1. Rest your thumb and wrist—avoid repetitive gripping for at least a week.

2. Use a thumb spica splint to keep your tendons from rubbing excessively.

3. Apply cold packs for 15 minutes at a time, twice daily, and consider topical anti-inflammatory gels.

For joint or cartilage strain (TFCC or arthritis):

1. Don't over-restrict motion—gentle circular wrist exercises improve blood flow.

2. Switch to ergonomic grips for daily tools, such as wide-handled pens or utensils.

3. Practice neutral wrist positioning—keep your hand aligned with your forearm when typing or lifting.

If symptoms persist for more than two weeks, an orthopedic or hand specialist can confirm the cause using ultrasound or MRI. Sometimes, short-term wrist braces or guided rehab exercises can prevent chronic damage.

5. Avoid the Common Mistakes Everyone Makes

1. "It's just a sprain." Many people dismiss the early warning signs. By the time they seek help, inflammation may have thickened the tendon sheath, requiring longer recovery.

2. "Pain patches fix everything." Topical pain relief can mask symptoms but doesn't treat the root cause. Without correcting movement patterns, the pain often returns.

3. "Rest means no movement at all." While rest is essential for tendons, total immobility can stiffen joints. Gentle range-of-motion exercises are key for recovery.

Small changes—like supporting your wrist properly, spreading tasks evenly between hands, and warming up before exercise—can prevent weeks of discomfort.

The truth is, not all wrist pain is created equal. The same patch or cream won't fix two entirely different issues. So the next time your thumb aches when twisting a bottle cap, don't just grab the nearest pain gel. Take a closer look at what your body's really saying—it's often more specific than you think.
