Five Types, Five Different Clocks
Arthritis in the hand isn’t one disease. The main types are osteoarthritis (wear, in the end joints, middle joints and thumb base), rheumatoid and psoriatic arthritis (inflammation, in the knuckles, wrists or a whole swollen finger), gout (one joint, suddenly red and hot) and post-injury arthritis (one joint, years after a fracture or torn ligament). Which type you have decides who treats it and how fast. Wear is managed over years. Inflammation has a treatment window measured in months.
“It’s just arthritis”
Somebody’s probably said it to you already.
Maybe a friend. Maybe a quick consult. Maybe you said it to yourself, rubbing your knuckles at 2am.
The problem is the word “just”.
Cos “arthritis” only means a joint is inflamed or worn. It’s a description, not a diagnosis…like being told your car is “making a noise”.
The word “arthritis” tells you the joint is unhappy. The TYPE tells you how much time you have.
What getting the type wrong costs
Here’s where it goes wrong, and it goes wrong in both directions.
Rheumatoid arthritis mistaken for wear and tear…and someone spends a year on heat packs and hand cream while the inflammation eats into cartilage. Cartilage that’s gone doesn’t grow back. The medication that could have stopped it works best in the first few months.
Thumb base arthritis treated as “tendonitis” for months. Wrong splint, wrong exercises, same pain.
Wear and tear treated like an emergency…and someone stops using the hand out of fear. Months of guarding later, they’ve got a stiff, weak hand ON TOP of the arthritis.
Same word. Completely different clocks.
Wear is managed over YEARS. Inflammation is treated in MONTHS. Mix them up and you lose either your joints or your nerve.
Four questions that sort it
1. Which joints?
- End joints near the nails, middle joints, base of the thumb: points to wear (osteoarthritis)
- Big knuckles at the base of the fingers, wrists: points to inflammation (rheumatoid)
- A whole finger swollen end to end: points to psoriatic arthritis
- Just one joint: gout, an old injury, or infection
2. What does the swelling feel like?
- Hard and bony, like a knob of bone: wear
- Soft, puffy, a bit warm: inflammation
- Red, hot, shiny, can’t bear the bedsheet touching it: gout or infection
3. How long are you stiff in the morning?
- Loosens in MINUTES, usually under half an hour: wear
- An HOUR or more, sometimes most of the morning: inflammation
4. How did it start, and is it one hand or both?
- Slowly over years, lopsided, past 45: wear
- Over weeks to months, both hands doing the same thing, tired and unwell with it: inflammation
- Overnight, one joint: gout
- One joint that was injured years ago and never felt quite right since: post-injury arthritis
(Try this: squeeze gently across all four knuckles at once, like a firm handshake. If that squeeze hurts on BOTH hands, tell your doctor exactly that. It’s one of the simple screening signs for inflammatory arthritis.)
Osteoarthritis: the common one
Cartilage wear in three favorite spots: the end joints, the middle joints and the base of the thumb. Knobbly bumps, aching after use, stiffness that loosens quickly. Runs strongly in families…if your mother had the knobbly fingers, that’s a better predictor than your job.
The window: before a joint stiffens into a bent position. Pain often settles over the years. Lost range doesn’t come back.
Read next: hand osteoarthritis, finger osteoarthritis and Heberden’s nodes, and thumb base arthritis, the one that actually stops people working. For the thumb, exercises and joint protection and the short thumb splint.
Rheumatoid arthritis: the urgent one
The immune system attacks the lining of the joints. Puffy knuckles and wrists, both hands, stiff for an hour or more, often tired and unwell with it. Any adult age.
The window: the first few months. That’s when medication does the most protecting. The first appointment is a doctor and blood tests…not a hand therapist, not a splint.
Read next: rheumatoid arthritis in the hands, and stiff, swollen fingers in the morning.
Psoriatic arthritis: the sausage finger
Inflammatory, like rheumatoid, but with its own fingerprints: a whole finger swollen like a sausage, pitted or lifting nails, and often (not always) psoriasis on the skin. It can hit the end joints, which is why it gets mistaken for wear.
The window: same as rheumatoid. Months, not years. Doctor first.
Read next: psoriatic arthritis in the hands.
Gout: the overnight one
Crystals in the joint. One joint goes red, hot, swollen and exquisitely painful, often overnight. Less common in the hand than the big toe, but it happens…especially in people who’ve had it elsewhere.
The window: hours to days, to settle the attack, and then long-term to stop the next one. And it can look IDENTICAL to a joint infection, which is a same-day problem. If you’ve never had gout before, don’t self-diagnose this one.

Post-injury arthritis: the one with a history
One joint that was broken, dislocated or torn years ago, and has been quietly wearing out since. The wrist is the classic: an old ligament tear or scaphoid fracture that was never fully treated, turning into arthritis a decade later. The elbow does it too.
The window: honestly, it was the original injury. Now it’s management…and protecting the joints around it.
Read next: wrist arthritis and elbow osteoarthritis.
What helps arthritis in the hand, whatever the type
Each type has its own treatment. But these help across the board:
- Daily motion. Full fist, full open, every day. Joints that move stay usable. Joints that are guarded stiffen faster
- Heat for stiff joints. Warm water before activity loosens things up. NOT for a joint that’s already hot and red. Ice or heat?
- Change the tool, not the hand. Fat-handled pens, jar openers, lever taps, two hands for the kettle. Less force through the joint on every repetition, all day long
- Splints, for the right joint and the right hours. Resting splints for flares, ring splints for drifting finger joints, thumb splints at night for the thumb base
- Strength. The muscles around a worn joint act as a brace. Boring, effective
- Injections and surgery, for the joint that fails all of the above. How many injections is too many, finger joint replacement, fusion, and trapeziectomy for the thumb base
The Tin Man only needed an oil can.
You need to know which kind of rusty you are first…cos the oil can for one type is the wrong move for another.
The short version
Knobbly end joints, thumb base, stiff for minutes: wear. Manage it over years, keep it moving.
Puffy knuckles on both hands, stiff for an hour, feeling unwell: inflammation. Doctor and bloods this month.
One joint red and hot overnight: gout or infection. Same day.
Not sure it’s arthritis at all? Finger joint pain by location and hand pain around perimenopause cover the lookalikes.
Want to know where your joints sit in their window right now…open, closing, or shut? The Closing Window Chart just below maps 15 hand conditions on one page, with the red flags that mean “don’t wait”. It’s free.
Written by Nigel Chua, hand occupational therapist in practice since 2005. Thousands of hands, wrists and elbows assessed and treated. My credentials are here. Every article on this site is written using the Closing Window Method: name the window your condition runs on, find where you are in it, and act while it’s still open. This page sorts the types; it doesn’t diagnose you. Swollen knuckles on both hands, or a joint that’s suddenly red and hot, need a doctor first.
