Arthritis in the fingers is not one condition. Osteoarthritis attacks the joints nearest the nails and the base of the thumb, producing hard bony swelling. Inflammatory arthritis attacks the big knuckles and the middle joints, with soft warm swelling and morning stiffness lasting over an hour.
Almost every British page on this subject lists the symptoms then tells you to see a GP. None teaches you to read your own hand. That is what follows, row of joints by row of joints.
Three rows of joints, three different diagnoses
End joints, nearest the nail
The classic site of osteoarthritis. Hard bumps called Heberden’s nodes, a sideways drift of the fingertip, and a joint that grinds rather than swells.
Middle joints
Osteoarthritis gives Bouchard’s nodes here. Rheumatoid arthritis also targets this row, but with soft warm swelling and long morning stiffness.
Big knuckles and thumb base
Swelling across the big knuckles of several fingers at once is inflammatory until proved otherwise. The thumb base, on its own, is almost always osteoarthritis.
Each finger has three joints: the one nearest the nail, the one in the middle, and the big knuckle where the finger meets the hand. Which row hurts is not random, and it is the most informative thing about your hand.
Osteoarthritis is a wear and repair process in cartilage, and in the hand it settles in the end joints and the thumb base, where load per square millimetre is highest. Rheumatoid arthritis is an immune attack on the joint lining, and it characteristically spares the end joints while inflaming the big knuckles on both hands. Pain at the thumb base that is worst gripping, and that lights up when you tuck the thumb into a fist and bend the wrist away from it, is more often de Quervain’s tenosynovitis, a tendon problem, particularly in the months after a baby arrives.
Heberden’s nodes are bone, not swelling
The hard bumps on the end joints have a name: Heberden’s nodes, after the eighteenth century London physician William Heberden. On the middle joints they are Bouchard’s nodes. Both are new bone, spurs formed at the joint margin as cartilage thins.
This matters practically. Bony nodes do not go down with an anti-inflammatory, because nothing is inflamed. They also stop hurting: the joint typically aches for a year or two while the node forms, then quietens permanently, leaving a finger that looks worse than it feels.
Osteoarthritis or inflammatory arthritis?
Two conditions, two ways of behaving
Osteoarthritis in the fingers
- Stiffness on waking that eases within twenty or thirty minutes.
- Hard, bony swelling that you can feel through the skin.
- End joints and thumb base first, often asymmetrical.
- Pain worse after using the hand, better with rest.
- Blood tests are usually normal.
Inflammatory arthritis
- Stiffness on waking that runs past an hour, sometimes all morning.
- Soft, warm, puffy swelling across the whole finger.
- Big knuckles and middle joints, often the same fingers on both hands.
- Pain worse at rest and overnight, easier once you get moving.
- Inflammatory markers and specific antibodies can be raised.
Morning stiffness separates them fastest. Osteoarthritic fingers are stiff for ten or twenty minutes and then loosen. Inflammatory joints stay stiff for an hour or more, and the stiffness returns after any long spell sitting still. The quiet kind of inflammation is a third thing again: it produces no stiffness at all, and is read off a number rather than off a joint.
Psoriatic arthritis is the exception that confuses everybody, because it can attack the end joints exactly like osteoarthritis. The giveaways are the nails, pitted or lifting from the bed, and dactylitis, where a whole finger swells uniformly instead of one joint.
| Where it hurts | Most likely cause | What else to look for |
|---|---|---|
| End joints only | Osteoarthritis | Hard nodes, fingertip drifting sideways |
| End joints plus nail changes | Psoriatic arthritis | Pitting or lifting of the nail, a whole finger swollen like a sausage |
| Big knuckles, both hands | Rheumatoid arthritis | Long morning stiffness, fatigue, soft warm swelling |
| Thumb base, one side | Thumb base osteoarthritis | Pain gripping a kettle, turning a key, opening a jar |
| One joint, red hot, sudden | Gout or infection | Onset over hours, skin red and shiny, same day GP appointment |
What happens when you see a GP
A GP examines the hands, asks about stiffness, and looks for the pattern above. Osteoarthritis in the fingers is diagnosed clinically in the UK. NICE guidance is explicit that imaging is not needed to confirm it when the presentation is typical, so do not be surprised if you leave without an X-ray.
If several joints are swollen and stiff, say so plainly and give the duration of the stiffness. That sentence triggers an urgent referral, and in inflammatory arthritis the first months of treatment shape the next twenty years.
What the NHS offers, in order
Exercise and hand therapy
NICE guideline NG226 puts tailored therapeutic exercise first for everyone with osteoarthritis, before any medicine. A hand therapist teaches grip and range of movement work you continue at home.
Topical anti-inflammatory gel
The first drug recommended, applied to the joint rather than swallowed. Fingers are close to the skin surface, which is exactly where topical treatment works best.
Splints and grip aids
A small thumb base splint for night use, and fatter handles on kettles and pens. Unglamorous, and often the change that makes the most difference to a working day.
Oral anti-inflammatories, briefly
Offered if the gel is not enough, at the lowest dose for the shortest time, with stomach protection where needed. Paracetamol is no longer routinely recommended for osteoarthritis.
Steroid injection or surgery
Discussed for a single joint that stays painful despite everything above. Fusing or replacing a finger joint is a considered decision, not a first move.
Grip, exercise and the things that actually change a day
The most useful change most people make has nothing to do with medicine. It is widening what they hold. A pen with a fat barrel, a kettle tipped from a stand, a jar opener screwed under a shelf. Every one reduces the pinch force through a worn thumb base. Adapted tools and exercise sit above every medicine in the treatment pathway for hand osteoarthritis, and they are the row most often skipped.
Movement is the other half. Hands that stop moving stiffen fast, grip strength falls, and lost grip limits people more than pain does. Short sessions several times a day beat one long one.
If you are weighing up supplements alongside all this, be clear about what the evidence supports. NICE tells clinicians not to offer glucosamine. Compounds with better data behind them, such as properly absorbed curcumin, sit in a different category: judge a bioavailable anti-inflammatory formula on absorption, not on the dose printed on the tub, and see what a supplement aimed at worn joints actually contains.
Red flags worth acting on
- A single joint that becomes red, hot and severely painful within hours. Gout and joint infection both look like this, and infection is an emergency.
- Morning stiffness lasting more than an hour, most days, for six weeks or longer.
- Swelling of several joints at once, especially the same ones on both hands.
- Fingers changing shape over months rather than years.
- Joint pain with unexplained fatigue, fever, or a new rash.
Frequently asked questions
What are the first signs of arthritis in your fingers?
Morning stiffness that loosens as you use the hand, an ache after gripping or writing, and a joint that looks slightly wider than its neighbour. Bony bumps on the joints nearest the nails, called Heberden’s nodes, appear later. Many people notice the change in a photograph first.
How do I know if my finger pain is arthritis or something else?
Arthritis pain sits in the joint itself, with visible swelling or a change in shape. Pain running along the finger, with tingling or numbness, points to a nerve or a tendon instead. A trigger finger clicks and catches as it bends.
Is finger arthritis osteoarthritis or rheumatoid arthritis?
Both exist, and the joints they attack differ. Osteoarthritis prefers the end joints nearest the nails and the base of the thumb, tends to be uneven between hands, and produces hard bony swelling. Rheumatoid arthritis prefers the big knuckles and the middle joints, usually mirrors itself on both hands, and produces soft warm swelling with morning stiffness lasting more than an hour.
Can you stop finger arthritis getting worse?
You cannot rebuild worn cartilage, but the course is not fixed. Keeping the joints moving maintains range and grip, losing excess weight lowers the inflammatory load, and protecting the joints during heavy tasks reduces flare ups. Inflammatory arthritis is different again: early treatment changes the long term outcome, which is why prompt referral matters.
Do hand exercises help arthritic fingers?
Yes, and they are the first thing recommended in the NICE osteoarthritis guideline. Gentle range of movement work keeps joints from stiffening, and grip strengthening protects the hand during daily tasks. Discomfort during exercise does not mean harm is being done, though sharp pain lingering into the next day means the load was too high.
What to take away
Look at your hands under a good light tonight, and note which row of joints is swollen and whether the swelling is hard or soft. Then time your stiffness tomorrow morning, from waking to the moment your hands work normally. The row and the clock are worth more at your first appointment than anything a scan will show.
