You put a hand out as you went down. Maybe you slipped on wet tiles, landed badly at netball or came off a bike. Now your wrist is swollen, sore to bend, and turning a door handle makes you wince. Nothing looks out of place, so you've been calling it a sprain.
Often, that's exactly what it is. But the same fall can cause an injury you really don't want to mistake for a sprain, so it's worth knowing the difference.
Ligaments are the tough bands that hold the bones of a joint together. A sprain is an injury to those ligaments and the capsule that wraps the joint 2. In the wrist, the usual cause is a sudden twist or wrenching movement, whether from a fall, a quick change of direction or repetitive strain 1.
How much damage is done decides the grade 1:
| Grade | What's happened to the ligament | What you tend to notice |
|---|---|---|
| 1 | A small number of fibres are torn | Mild pain, slight swelling |
| 2 | A partial tear | More swelling and tenderness, some loss of movement |
| 3 | A complete tear | Severe pain, swelling, an unstable wrist. A "pop" at the time may suggest this grade |
Common wrist sprain symptoms are swelling, heavy bruising, pain and tenderness, difficulty moving the wrist, weakness or instability, and sometimes a "pop" when it happened 1.
The grade matters because the risks run both ways. A moderate or severe sprain that isn't treated well can leave you with chronic ligament instability, a wrist that keeps feeling loose 1. But not using the wrist enough can lead to muscle wasting, and with a severe injury or too much rest, fibrosis can set in 1. Fibrosis is a build-up of thick, stiff, scar-like tissue. Good treatment sits between the two: protect it early, then get it moving and loaded again.
The scaphoid is a small bone on the thumb side of the wrist. After a fall onto an outstretched hand, a sore wrist needs proper assessment to rule out a scaphoid fracture 3.
The most sensitive clinical sign is tenderness in the anatomical snuffbox, the small hollow on the thumb side of the back of your wrist. Across 13 studies, it picked up 87 to 100% of scaphoid fractures 3. But its specificity ranged from 3% to 98%, so plenty of people with snuffbox tenderness turn out not to have a fracture 3. Combining tests helps, but the research is weak 3.
X-rays have a blind spot too. A normal first X-ray doesn't rule out a scaphoid fracture 4. In studies of people with a clear first X-ray whose fracture was still suspected, about one in five turned out to have one 4. Follow-up MRI, CT or a bone scan settles it, and catching it early lowers the risk of the bone not healing (non-union) while sparing people casts they don't need 4.
In practice: if the pain sits on the thumb side after a fall, get it assessed, even if you can still move your wrist and even if an X-ray was clear. If we think something needs imaging, we'll tell you plainly and point you to your GP.
Most wrist sprains are diagnosed from your story and an examination. You'll be asked what happened, what you're feeling and how long it's been going on, and about any earlier wrist injuries 1 5. Then the wrist is checked for pain, movement and instability, which is how the severity gets judged 1.
An X-ray can't show a ligament. It's there to rule out other injuries, although wrist bones that don't line up properly can be a sign of a ligament injury 1 5. If that still leaves questions, a doctor may suggest an MRI or ultrasound. Occasionally it's an arthroscopy, where a small camera goes inside the wrist to check for hidden damage 1.
First we work out what you've actually done: which part of the wrist is involved, roughly what grade it is, and whether anything else needs ruling out. We also ask what your wrist has to get back to, whether that's typing all day, lifting a toddler or taking your weight in a push-up.
To be upfront: we found no strong trials comparing physiotherapy approaches for simple wrist sprains. The approach above follows Australian government health guidance 1,2 and our own clinical reasoning, not a single trial-proven protocol.
A bandage or brace supports the wrist and helps bring down swelling. It should be snug without cutting off blood flow 1. Bracing is a recognised part of sprain treatment 2. We treat a wrist brace as a short-term support, not a replacement for rebuilding strength, since underuse brings its own problems 1.
It's listed for sprains generally 2, but we found no strong evidence it speeds recovery from a wrist sprain. If we use it, it's an add-on, never the plan.
The guidance differs. One source says paracetamol and anti-inflammatory medicines may help 1; another says some pain medicines can disrupt soft tissue healing 2. Physiotherapists don't prescribe medication, so check with your GP or pharmacist.
A sprained wrist is treated along The Well Motion Recovery Path™. The grade sets the pace 5, and you move up a phase when the wrist can do more, not when another week has passed.
How long it usually takes. Mild sprains often recover fully over several weeks, and moderate ones can take longer 5. After surgery for a complete tear, your surgeon sets the timeline: the ligament usually heals in 8 to 12 weeks, though full recovery can take 6 to 12 months 5. These figures are surgeons' guidance, not trial results.
Most wrist sprains come from a fall onto an outstretched hand 5, and one piece of protective gear has been properly tested against that:
Book an assessment rather than keep managing it yourself if:
Seek urgent help if you have pain or tightness in the muscles along with tingling, numbness or trouble moving the hand or wrist. That can be a sign of acute compartment syndrome, which is an emergency: call triple zero (000) 1.
If you're unsure whether it can wait, the healthdirect helpline (1800 022 222) is staffed by registered nurses 24 hours a day 1. For most people, though, a wrist sprain is a short detour, not a long-term problem.
We start by listening: how it began, what makes it worse, and what it's stopping you from doing. Then we examine the area, explain what we find in plain English, and agree a plan with you. Your first visit is 40 minutes at Engadine and 30 minutes at our other clinics.
We see patients at Engadine, Mount Annan, Narellan and Appin, and at home through our mobile physiotherapy service. If you have private health cover, here's how health fund rebates work for physiotherapy.
Most soft tissue injuries take a few weeks to heal, depending on how severe the sprain is and on things like weakness, stiffness or re-injury along the way 2. Milder sprains sit at the shorter end; a complete tear may need a surgeon's assessment 1. We won't give you a fixed number of weeks per grade, because the Australian guidance doesn't. If your sprained wrist recovery time is dragging on, get it reassessed.
Swelling, bruising, pain, tenderness and difficulty moving the wrist are the typical signs 1. The catch is that a scaphoid fracture can look very similar, and the first X-ray can miss it 4, so see the section above if the pain is on the thumb side.
A quick clarification: a strain is an injury to a muscle or tendon, and a sprain is an injury to a ligament 2. Both get the same first aid 2. Stay gently active without pushing into pain. Ice for 20 minutes every two waking hours, with a wet towel between ice and skin, and use compression and elevation 2. After two to three days, start gentle movement as pain allows 1.
For the first 72 hours, avoid heat, alcohol, running and firm, direct massage, because they can increase swelling 2. Don't wrap it so tightly that it cuts off circulation 1. And don't swing too far the other way: keeping it completely still for too long can lead to muscle wasting and stiff scar tissue 1.
A mild sprain can usually be managed at home, with a doctor's follow-up after about a week 1. But "managed at home" isn't the same as ignored. A moderate or severe sprain that isn't treated well can leave the wrist with chronic ligament instability 1. If it isn't clearly improving, have it looked at.
Numbness, tingling or pins and needles through your thumb, index and middle fingers, often worst overnight. It's a nerve compressed at the wrist, and there's usually plenty worth trying before surgery comes up.
