This site has three articles about the thumb side of the wrist and, until now, none about the other one. That is a fair reflection of how often each gets discussed and a poor reflection of how often each hurts.
Pain on the little finger side is common, and it has a recognisable set of provoking movements.
The movements that give it away
The location narrows it down. What provokes it narrows it considerably further, and most people can answer this without any prompting.
Three things come up almost every time, and together they point at the ulnar side more reliably than any description of the pain itself.
- Turning things. Keys, doorknobs, jar lids, screwdrivers. Rotation loads that side of the wrist directly.
- Pushing up from a chair. Weight through an extended wrist compresses it.
- Gripping with the wrist bent towards the little finger, which is most racquet and club sports.
- Clicking or clunking, which is common and less alarming than it sounds.
What actually sits there
Worth a paragraph, because the structure explains why rotation is the movement that hurts.
A small complex of cartilage and ligament bridges the gap between the end of the forearm bone on that side and the wrist bones. It cushions load and holds the two forearm bones together as they rotate.
It can be torn by a fall onto an outstretched hand, strained by repeated twisting, or simply worn with time. Where the forearm bones sit slightly unevenly relative to each other — which is a normal anatomical variation — that structure takes more load and wears sooner.
How it usually starts
Three routes in, and the history usually points clearly at one of them.
| How it began | Typical story | What that changes |
|---|---|---|
| A fall onto the hand | Sudden pain, sometimes a pop | Fracture needs excluding first |
| Repetitive twisting | Built over weeks with a new task or sport | Load management is the treatment |
| Gradual, with age | No injury, worse over months | Often degenerative rather than torn |
| After a wrist fracture | Pain persisting once the bone healed | Worth a specialist review |
| With clicking and instability | A sense the wrist gives way turning things | Assessment rather than self-management |
The scan caveat, again
It applies here as clearly as it does to the knee and the neck.
Tears in this structure are found on imaging in a substantial proportion of people with no wrist pain whatsoever, and the proportion climbs with age. A report describing a tear is not by itself an explanation of your symptoms, and it is certainly not an instruction to operate.
What the scan usefully does is rule out the things that genuinely need ruling out, particularly after a fall onto the hand. That is a real and important job, and a different one from explaining an ache.
What settles it
As with most of the hand and wrist, changing the load does more than anything applied to it.
| Measure | Why it helps | Note |
|---|---|---|
| Reduce rotation loads | Removes the provoking movement | Electric screwdriver, lever handles, jar opener |
| A brace that limits rotation | A general wrist splint does not | Ask for the right kind |
| Change how you push up | Use a fist or forearm rather than a flat hand | Small change, repeated dozens of times a day |
| Grip modification in sport | Thicker grip, technique review | Where the sport caused it |
| Graded strengthening | Forearm and grip, once settled | Later rather than first |
| Injection or surgery | For cases that do not settle | A hand specialist conversation |
Or is it something else?
Several things produce pain in the same small area, and they are managed differently.
- Numbness in the little and ring fingers points at a nerve rather than the joint — see the ulnar nerve note and a pinched nerve in the neck.
- A tendon that snaps over the bone when you rotate is a different problem in the same place.
- Thumb-side pain is de Quervain’s or thumb base arthritis, not this.
- Night pain with tingling into the thumb side is carpal tunnel syndrome.
The UVA Health patient library covers hand and wrist conditions if you want to read further before an appointment.
Where acupuncture and massage fit
As an adjunct to the load management, which is the same position this site takes on every tendon and joint problem where the mechanics are doing the work. Wrists are no exception, and the small size of the structures involved does not make needling any more decisive than it is elsewhere.
Needling and soft tissue work around the forearm can ease the pain and the muscular tightness that builds around a guarded wrist. It does not repair cartilage, and the change of grip and rotation is what actually settles it.
When to see a doctor
See a doctor for wrist pain after a fall, which needs a fracture excluded; for numbness or tingling in the hand; for a wrist that gives way or locks; for visible deformity or swelling with warmth; or for pain that has not improved after six to eight weeks of genuine load management.

Frequently asked questions
What causes pain on the little finger side of the wrist?
Most often the small cartilage complex that cushions and stabilises that side of the joint, injured by a fall onto the hand, by repeated twisting loads, or simply worn with age. Tendon and joint problems in the same area produce similar pain.
Which movements provoke it?
Rotation above all — turning a key, a doorknob, or a screwdriver. Pushing up from a chair is the other classic, because it loads that side of the wrist directly.
My scan shows a tear. Does that mean it needs fixing?
Not on its own. Tears in that structure are found regularly in people with no wrist symptoms at all, and the proportion rises with age. A scan describes structure; it does not establish the source of pain.
What kind of brace helps?
One that limits rotation rather than a general wrist splint that only stops bending. That distinction matters, because rotation is the movement doing the damage.
How long does it take?
Weeks to a few months for most straightforward cases managed sensibly. Longer if the provoking activity has continued unchanged, which is the usual reason it drags on.
