For a lot of people, stiff hands in the morning is one of the most common complaints they have when it comes to rheumatoid arthritis.
Especially when they think it goes away with time—and it doesn’t—that’s when most start wondering: why isn’t my hand pain going away?
Especially with rheumatoid arthritis, it’s not something that’s diagnosed on a single test.
It requires data from three ends: what your joints are doing, what your bloods show, and what imaging finds inside the joint.
Here’s all you need to know about rheumatoid arthritis, the diagnosis, how an ultrasound helps and how to book one in London.
What is rheumatoid arthritis, and how is it different from osteoarthritis?
Osteoarthritis is different. It’s wear and tear in the cartilage that builds up over years of use, and it isn’t driven by the immune system at all.
Rheumatoid arthritis can start at any age and often affects smaller joints like the hands, wrists and feet first, with morning stiffness that typically lasts more than an hour. Osteoarthritis is more common in middle-aged and older adults, tends to affect weight-bearing joints like the knees, hips and spine, and morning stiffness usually improves within 20 to 30 minutes.
And here’s the interesting bit: the treatments have nothing in common. Osteoarthritis is managed with exercise, weight management and pain relief. Rheumatoid arthritis needs medication that calms the immune response, started as early as possible, because the joint damage it causes doesn’t reverse.
What are the early signs to look out for?
Early rheumatoid arthritis is easy to dismiss, because it starts small and it comes and goes.
The pattern clinicians look for is joint pain and swelling that has lasted more than six weeks, affects several joints rather than one, involves the small joints of the hands or feet, and comes with morning stiffness lasting longer than 45 minutes.
Symmetry is a useful clue. If both index knuckles are sore, or both wrists, that points more strongly towards an inflammatory cause than a single painful joint does.
How is rheumatoid arthritis diagnosed?
Here’s the thing: there’s no single test that gives you a yes or no answer. Diagnosis comes from putting three pieces together.
Clinical examination
A clinician checks which joints are swollen and tender, how many are involved, whether the pattern is symmetrical, and how long stiffness lasts. This is the backbone of the diagnosis, and no test replaces it.
Blood tests
These look for inflammation and for the antibodies associated with rheumatoid arthritis. The NHS puts the limitation plainly: no blood test can definitively prove or rule out a diagnosis of rheumatoid arthritis, but several tests can show indications of the condition.
Imaging
X-rays show damage that has already happened. Ultrasound shows inflammation that is happening now, which is why it has become the imaging test used earliest in the pathway.
| Blood test | What it’s looking for |
|---|---|
| Rheumatoid factor (RF) | An antibody linked to RA. More than half of all people with rheumatoid arthritis have high levels at the start, but about 1 in 20 people without RA also test positive. |
| Anti-CCP antibodies | More specific to RA. People testing positive are very likely to develop rheumatoid arthritis, but not everybody with RA has this antibody. |
| CRP and ESR | General markers of inflammation anywhere in the body. |
| Full blood count | Checks for anaemia, which often accompanies RA, and helps exclude other causes. |
| ANA | Screens for other autoimmune conditions that can look similar. |
| Uric acid | Checks for gout, which can mimic inflammatory arthritis. |

Our rheumatology screening brings all three together
The blood panel, joint ultrasound, and a GP consultation that reads the results side by side rather than in isolation.
Book Rheumatology ScreeningCan an ultrasound detect rheumatoid arthritis?
Here’s the thing: an ultrasound can’t hand you the diagnosis on its own. What it can do is see the inflammation that blood tests only hint at, and see it before an X-ray would show anything at all.
A probe goes over the joint and produces a live picture of the synovium, the tendons and the joint surface. The clinician looks for four things.
Synovitis
The joint lining is thickened, and there’s fluid in the joint. This is the core finding in rheumatoid arthritis, and it’s what greyscale ultrasound measures when it assesses synovial hypertrophy and effusion.
Power Doppler signal
This is the part patients find most interesting. Power Doppler detects blood flow, and inflamed synovium develops new blood vessels, so an active joint lights up with colour on the screen. Thickened lining with no Doppler signal reads differently from thickened lining with a lot of it.
Tenosynovitis
Inflammation of the tendon sheaths running through the wrist and fingers. It often turns up early in rheumatoid arthritis, and it’s easy to miss on examination alone.
Bone erosions
Small breaks in the bone surface at the joint edge. Ultrasound picks these up earlier than X-rays, though MRI is still the most sensitive for very early changes.
Which joints get scanned for rheumatoid arthritis?
For a scan that’s looking at rheumatoid arthritis, there are some specific starting points, and the ultrasound scan starts with them first:
Hands and wrists
The knuckles (especially the second and third), the middle finger joints, and the wrist are where early synovitis and tenosynovitis usually appear. That’s why a hand and wrist ultrasound is the most common request.
Feet
The joints at the base of the toes (the metatarsophalangeal or MTP joints) are affected early and often, sometimes before the hands become obviously swollen. The fifth MTP joint is frequently the very first site of involvement. So a foot ultrasound is worth considering if that’s where your pain started.
Knees, shoulders and elbows
These tend to be involved later in the disease course, though they’re still part of the standard 28-joint assessment used in rheumatology.
Need a scan for a specific joint?
At London Private Ultrasound, we offer private ultrasound scans for knees, shoulders and elbows, with same-day appointments, results explained on the day and a written report within 24 hours. Available at our Harley Street and St Albans clinics.
Who actually makes the diagnosis for rheumatoid arthritis?
A rheumatologist makes the formal diagnosis of rheumatoid arthritis and prescribes the medication that treats it. That’s true whether you go through the NHS or privately.
A scan and screening panel put objective findings in your hands so referral happens faster and with something behind it. Our private GP clinic can write that referral and send your results on.
What happens after the scan?
If the findings point towards inflammatory arthritis, the next step is a rheumatology opinion and, usually, starting a disease-modifying medication. Treatment aims to bring the inflammation down and keep it down, because that’s what protects the joint over the long run.
If the findings point towards osteoarthritis, a tendon problem or something mechanical, the path looks completely different. Our Joint Pain Clinic handles guided injections, rehabilitation and MSK specialist review in the same building.
Either way, you leave knowing which of those two roads you’re on.
Book a joint ultrasound and rheumatology screening in London
Joint pain is one of the most neglected symptoms people live with.
You put up with the stiffness, you swap out activities, you tell yourself it’s just age or overuse. But joint inflammation is the one thing that costs you more the longer you leave it. We believe that early diagnosis and treatment protect your joints from permanent damage. That’s why we’ve made this pathway accessible for people in London.
At London Private Ultrasound, we offer all of these services, so you can come in based on your specific needs. Our team is welcoming, and we’re open seven days a week.
Both clinics are a short walk from the Tube: 27 Welbeck Street in the Harley Street medical district (minutes from Bond Street and Oxford Circus), plus 54–56 Victoria Street in St Albans.

Joint Pain ClinicFrequently asked questions
Can arthritis be detected by ultrasound?
Ultrasound detects the changes arthritis causes: synovitis, joint effusion, tenosynovitis and bone erosions, along with the increased blood flow that marks active inflammation. It’s particularly good at picking up inflammatory arthritis early, before an X-ray would show anything.
Does ultrasound show inflammation?
Yes, and this is where it does its best work. Greyscale imaging shows the thickened joint lining and any fluid. Power Doppler shows blood flow within that lining, which is how active inflammation is distinguished from old, settled changes.
Does rheumatoid arthritis show up on ultrasound if my blood tests are normal?
It can. Seronegative rheumatoid arthritis, where both rheumatoid factor and anti-CCP come back negative, is well recognised, and the joints are inflamed regardless of what the bloods say. Ultrasound looks at the joint directly, so synovitis with an active Doppler signal is visible whether or not you have the antibodies.
How common is rheumatoid arthritis in the UK?
It’s the most common form of inflammatory arthritis. The NHS notes it’s more likely if you’re a woman, have a family history of it, or smoke, and that it usually affects the hands, feet and wrists first.
Does arthritis pain come and go?
Rheumatoid arthritis pain typically fluctuates, with flares where several joints become swollen and stiff, and quieter periods in between.
How is rheumatoid arthritis treated in the UK?
Treatment is led by a rheumatology service and centres on disease-modifying medication started as early as possible, alongside physiotherapy, occupational therapy and pain management. The aim is to suppress the inflammation and keep it suppressed, since that’s what prevents lasting joint damage.
Is there a best diet for rheumatoid arthritis?
No diet treats rheumatoid arthritis or replaces medication. A balanced diet supports general health and helps with weight management, which reduces load on affected joints, and your rheumatology team can refer you to a dietitian if you want specific guidance. Be cautious with anything marketed as a cure.
What are the NHS waiting times for rheumatology?
NICE says a GP should refer suspected persistent synovitis to rheumatology within 3 working days. How long you then wait for the appointment varies considerably between trusts, and you can check your local figures on the NHS My Planned Care website.
Do I need a GP referral for a joint ultrasound?
No. You can book directly. If you’d like your results sent on to your GP, rheumatologist or physiotherapist, just tell us on the day.
