Knobbly Joints, Stiff Mornings, a Thumb That Won’t Open Jars. Here’s the Map.
Hand osteoarthritis is cartilage wear in three specific places, not the whole hand: the last joint of the fingers, the middle joint, and the base of the thumb.
There is no cure. But the pain usually comes in phases, often a year or two of aching per joint, then a stiffer, knobblier, much quieter joint that still works.
What helps: heat, daily movement, smarter tools, a splint during flares, and strength work. Injections and surgery are for the few joints that fail all of that.
The outcome is far more changeable than people are told, because most of the disability comes from stiffness, grip habits and swelling… and all three of those are treatable, for years, long after the X-ray has stopped looking pretty.
Here’s what you’re probably living with. Fingers that take a few minutes to loosen in the morning. Bumps on the knuckles nearest your nails. Jars handed over to someone else. Rings that don’t go over the knuckle anymore.
And here’s what goes wrong. People wait for the pain to tell them when to act. By the time it’s bad enough, a joint has quietly set bent, and a bent joint doesn’t come back.
What is hand osteoarthritis?
Every joint in your hand is lined with cartilage, a smooth, slippery bearing surface. In osteoarthritis that cartilage thins over the years. The bone underneath responds by remodeling and building little bony lips at the edges of the joint, which are the knobs you can see and feel.
Along the way the joint gets inflamed, achy and stiff. Later, it usually goes quiet.
It’s very common from the 40s and 50s onward, more so in women, often first noticed around menopause, and it strongly runs in families. See perimenopause and hand pain.
Which joints does hand osteoarthritis affect?
Osteoarthritis in the hand is not random.
It picks the DIP joint, the last one before the fingernail, and builds the bony knobs called Heberden’s nodes.
It picks the PIP joint, the middle one, where the same knobs are called Bouchard’s nodes.
And it loves the base of the thumb, the CMC joint, which is the one that actually stops people working. Opening jars. Turning keys. Holding a pen for more than twenty minutes.
What it usually spares are the big knuckles, the MCP joints. (Joint names explained in MCP, PIP and DIP joints.)
That distribution is the whole diagnosis. Swelling across the big knuckles of BOTH hands, with morning stiffness past the hour mark, is not osteoarthritis… that’s the pattern of rheumatoid arthritis, and the two run on completely different clocks.
One you manage over decades.
The other has a treatment window measured in months.
(In clinic I ask people to point, not describe. Where the finger lands tells me more than ten minutes of history.)
Hand osteoarthritis symptoms
- Morning stiffness that loosens in minutes, usually under 30. Over an hour points somewhere else.
- Aching after use, often worse in the evening or the day after a heavy job.
- Hard, bony knobs at the end or middle finger joints. They don’t go away.
- Flares, when a joint goes red, warm and tender for weeks, then calms down.
- Fine tasks getting grumpy: buttons, jewelry clasps, jar lids, pinching a coin out of a purse.
- At the thumb base: a deep ache with pinching, and later a squared-off look where the thumb meets the wrist.
- Later on: a fingertip that drifts sideways or droops, or a finger that won’t fully straighten.
How is it diagnosed?
- Look and feel. Hard nodes at the end or middle joints, a sore thumb base, short morning stiffness, aged 40-plus. That’s usually enough for a confident diagnosis.
- X-ray shows narrowed joint spaces and bony spurs. Useful if surgery is on the table or the pattern isn’t typical. How bad the X-ray looks doesn’t match how much it hurts very well.
- Blood tests are normal in osteoarthritis. They’re done when rheumatoid or psoriatic arthritis is a possibility.
A smaller group get erosive hand osteoarthritis, an angrier version that hits the middle joints hard and stays red and swollen for months. Still osteoarthritis, still normal blood tests, but worth a proper diagnosis. More in the finger osteoarthritis article linked above.
Did I cause this by using my hands?
No.
I get asked this every single week, usually by someone who has already decided the answer is yes and has quietly stopped doing something they love.
Typing does not cause hand osteoarthritis.
Knitting does not. (Okay, maybe a little strain on the soft tissues around the joint, but that’s a separate, related issue.)
Cracking your knuckles does not.
Genetics, age, previous injury and hormonal change do most of the work. If your mother had knobbly finger joints, that is a far stronger predictor than your job.
What heavy use DOES change is how much a worn joint hurts on a given day. Load provokes symptoms. It doesn’t create the disease.
Use does not wear the joint out. Use decides how loud the joint is about the wear it already has.
This distinction matters, because the people who do worst are the ones who protected the hand out of fear. Six months of guarding gives you a stiff, weak, painful hand ON TOP of the arthritis.
Now you have two problems, and I can only fix one of them.
Does hand osteoarthritis get worse? The window that’s actually open
People assume the window closed when the cartilage went. It didn’t.
The window here is the phase where a joint is INFLAMED and stiffening but has not yet settled into a fixed position. That phase often runs a year or two per joint, sometimes longer, and it’s where almost all the useful work happens.
- Early, angry phase (OPEN): joint is swollen, warm, aching at night, grip is dropping. Splinting, load change and pacing do the most work here. Range is still there to protect.
- Middle phase (CLOSING): pain is settling but the joint is losing movement and the knobs are permanent. Daily movement, strength work and joint-protection habits are what hold function.
- Late phase (SHUT for position, often quiet for pain): many DIP and PIP joints go quiet. They stay knobbly and stiff, but they stop hurting. The thumb base is the one that often doesn’t, and that’s the joint that ends up in surgery.
A joint that has stiffened in a bad position does not come back.
That’s the only genuinely irreversible thing in this article, and it’s the thing nobody is warned about.
What actually helps, ranked honestly
Changing the tool, not the hand. Fat-handled pens, jar openers, lever faucets, a kettle you tip rather than lift, a key turner, spring-loaded scissors. This is unglamorous and yet it is the cheapest AND highest-yield intervention I have. It reduces the force through a worn joint on every repetition, all day, without you thinking about it.
Heat before, not ice. Osteoarthritic hands generally move better warm. Warm (not hot) water for 10 to 15 minutes in the morning or before a fiddly job, then move the fingers while they’re warm. Ice is for the flare, not the routine. See ice or heat for hand pain.
Anti-inflammatory gel rubbed onto the sore joints is a sensible first medicine for small hand joints, if your doctor or pharmacist agrees. Pills for short spells during flares, with your doctor’s guidance.
A splint during flares. Small splints rest an angry joint while it calms down. They don’t fix the joint. Details below.
Movement and strength work, done boringly. Daily range to keep the joints moving, then putty, grip work and thumb exercises. The muscles around the thumb base act as a dynamic brace. Stronger muscles mean less shear through the joint.
Injection. Can settle a badly flared single joint for weeks to a few months, sometimes longer. Worth it when a flare is stopping you working. Not a plan on its own, and the small joints don’t take repeated injections well.
Surgery, last. For the thumb base, that’s usually a trapeziectomy. For a destroyed finger joint, it’s a choice between a replacement, which buys movement, and a fusion, which buys silence. You don’t get both. Anyone who tells you otherwise is selling something.
Splints for hand osteoarthritis
- Thumb base (CMC): a short, hand-based thumb CMC splint that holds the base joint and leaves the wrist and thumb tip free. In a flare, most of the day for 2 to 4 weeks. After that, for the jobs that hurt and at night if you wake sore.
- End joint (DIP): a small splint holding just the end joint straight, at night and for aggravating tasks, for a few weeks through a flare.
- Middle joint (PIP) drifting sideways: slim figure-of-eight ring splints in the day, so pinch is steadier and less painful. They won’t straighten a joint that’s already set crooked.
The trick nobody tells you: splint in the flare, move it the rest of the time. A joint splinted all day, every day, for months gets weaker and stiffer, not happier.
Exercises for arthritis in the hands
Do these once or twice a day, ideally after heat. A mild ache during is fine. Pain that’s worse the next morning means do fewer.
- Full fist, full open. Make a gentle full fist, then spread the fingers wide and straight. 10 times.
- Tendon glides. Straight fingers, hook fist, full fist, tabletop, straight fist. Hold each 3 seconds, 5 to 10 rounds.
- Thumb to each fingertip. Make an “O” with the thumb and each finger in turn, keeping the O round, not collapsed. 5 rounds.
- Finger straightening. Hand flat on a table, press each finger down flat one at a time and hold 5 seconds. 5 per finger. This is the one that guards against a joint setting bent.
- Thumb web stretch. Gently open the thumb away from the index finger, hold 20 to 30 seconds, 3 times.
- Light grip work once a flare has settled: soft putty or a sponge squeeze, a minute or two a day.
Avoid hard putty, grip trainers and heavy key pinch on a sore thumb base. Full thumb program in thumb arthritis exercises.
Living with it: work, driving, hobbies
- Desk work: a fatter pen or a stylus, a mouse that fills the palm, voice typing for long emails, short breaks to open the hands every half hour or so.
- Driving: hold the wheel with an open palm rather than a tight wrapped grip. A key turner for older cars.
- Kitchen: two hands on the kettle and pots, an under-cabinet jar opener, an electric can opener, slide instead of pinch-and-lift.
- Gardening and DIY: padded gloves, fat-handled tools, ratchet pruners, short sessions.
- Knitting, music, crafts: keep doing them. Thicker needles, 20 to 30 minute blocks, warm the hands first.
- Gym: fat grips or lifting straps for pulling, and a neutral grip if the thumb base complains.
Things that get mistaken for it
A small cyst sitting on top of an arthritic DIP joint, leaving a groove down the nail, is a mucous cyst, a symptom of the arthritis, not a separate disease. Don’t pop it.
One finger joint suddenly red, hot and screaming overnight is not arthritis behaving badly. That’s gout until proven otherwise, and it can look identical to an infection.
Psoriasis on the skin, pitted nails, or a whole finger swollen like a sausage points to psoriatic arthritis, which can also hit the end joints.
And a hand that has gone stiff across ALL the joints after a cast or an injury is post-immobilization stiffness, which is a different problem with a much better ending.

What a hand therapist does differently
- Works out which joints are in which phase, cos the plan for an angry joint is different from the plan for a quiet one.
- Fits splints to your joints and your day, so they actually get worn.
- Looks at what you’ve stopped doing and finds a way back into it, with tools, grips or a different method.
- Measures grip and pinch, so you see progress before you feel it. More in what a hand therapist actually does.
Get it checked today if
- A single joint is suddenly red, hot, very swollen and too painful to touch, especially with a fever or a nearby cut or popped cyst. That can be infection or gout, not arthritis.
Get it checked if
- Both hands are swollen across the big knuckles with morning stiffness over an hour.
- Psoriasis, pitted nails, or a whole finger swollen like a sausage.
- Your thumb base pain is now stopping you working or driving.
- You’ve started avoiding everyday tasks because of your hands.
- A finger is starting to hold a bent position it won’t fully straighten from.
That last one is the quiet one. It’s the point where “I’ll live with it” becomes “I’ve lost it”.
Thanos had a whole gauntlet. You have ten joints that matter, and most of them still work… but only if you use them while the using is still possible.
Pain in an arthritic hand is a nuisance. Lost range is a deadline.
Written by Nigel Chua, hand occupational therapist in practice since 2005. Thousands of hands, wrists and elbows assessed and treated. My credentials are here. This article explains; it doesn’t examine. If a joint is stiffening rather than just aching, get assessed by a hand therapist. That’s the appointment that changes what your hand looks like in five years.
