In short
Scleroderma rarely announces itself with tight skin. It usually begins with fingers that change colour in the cold, hands that feel puffy, and reflux that is new and persistent. Recognising that combination early matters, because the treatments that protect the lungs and kidneys work best before damage is established.
Scleroderma — systemic sclerosis — is uncommon, and the name describes the late appearance rather than the early one. By the time skin is visibly tight and shiny, the disease has usually been present for a while.
The early signs are ordinary enough that each on its own means very little. It is the combination that matters.
The first sign, almost always
Raynaud's phenomenon: fingers that change colour in the cold or with stress — classically white, then blue, then red as they warm — with numbness, and often pain as they recover.
Raynaud's is common and usually harmless. Most people who have it, particularly young women with a history going back to their teens, have primary Raynaud's and never develop anything else. Raynaud's and cold hands covers the common form in detail.
What raises concern is Raynaud's that:
- Starts after about thirty, rather than in the teens
- Is severe — attacks lasting a long time, extremely painful, or triggered by mild cold
- Causes ulcers, pits or scars on the fingertips, or areas of blackened skin
- Is asymmetrical between the two hands
- Comes with other symptoms from the list below
Fingertip ulcers in particular should always be assessed. They are not a feature of ordinary Raynaud's.
Puffy fingers
An early and easily dismissed sign. The fingers feel swollen and stiff, particularly in the morning; rings become tight; a fist is harder to make. The skin is not yet tight, just doughy.
This stage is often attributed to fluid retention, salt, or early arthritis. It can last months. Noticing it, alongside Raynaud's, is one of the most useful things a doctor can do.
Reflux that is new and persistent
The oesophagus is affected early and very commonly. The muscle of the lower oesophagus weakens, so acid comes up and food is slow to go down.
What suggests it is more than ordinary acidity:
- Heartburn that is new in an adult and does not settle with the usual measures
- A sensation of food sticking in the chest
- Worse lying flat, waking at night
- Needing acid-suppressing medicines continuously rather than occasionally
Many people have reflux. Few have reflux alongside colour-changing fingers and puffy hands — and that trio is the one worth acting on.
The other early features
- Skin changes beginning at the fingers. Tightening starts distally and moves proximally. Difficulty pinching the skin on the back of a finger is an early sign.
- Telangiectasia — small flat red marks on the face, lips and hands, like tiny spider-webs of vessels.
- Calcinosis — hard chalky lumps under the skin, often at the fingertips or elbows, which may break through and discharge white material.
- Breathlessness on exertion or a dry cough, which may mean lung involvement — see autoimmune interstitial lung disease. This is the one that changes the outlook most, and it can be present before symptoms are obvious.
- Joint pain and stiffness, and sometimes a creaking felt over tendons.
- Difficulty opening the mouth fully, as facial skin tightens.
- Fatigue and weight loss.
The test that helps most
Nailfold capillaroscopy examines the tiny blood vessels at the base of the fingernail under magnification. In primary Raynaud's they look normal. In scleroderma and related conditions they are enlarged, distorted, and in places missing altogether.
It is painless, takes minutes, and is one of the most useful tests in distinguishing harmless Raynaud's from the kind that needs following. The clinic offers it — see nailfold capillaroscopy.
Alongside it: ANA, and if positive, the specific antibodies — anti-centromere, anti-Scl-70 (topoisomerase I) and anti-RNA polymerase III. These matter because they predict what to watch for. Anti-Scl-70 is associated with lung fibrosis; anti-RNA polymerase III with a particular kidney complication and with more rapid skin involvement. What a positive ANA means explains the general test.
Why early recognition changes things
Scleroderma is not curable, and that is worth stating plainly. What has changed is how much of the damage can be prevented or slowed.
- Lung fibrosis is treatable, and treatment works far better before extensive scarring. Screening with lung function tests and a high-resolution CT is done at diagnosis, not when breathlessness appears.
- Pulmonary hypertension is screened for with an echocardiogram, periodically, because treatment outcomes depend on early detection.
- Scleroderma renal crisis — a sudden, dangerous rise in blood pressure with kidney failure — is treated with ACE inhibitors and is a medical emergency. Knowing you are at risk, and monitoring blood pressure at home, changes outcomes. High-dose steroids can precipitate it, which is why steroids are used cautiously in scleroderma.
- Digital ulcers can be prevented and treated with vasodilators rather than allowed to progress.
None of that is possible for someone whose disease has not been recognised.
What happens at the first assessment
Knowing what to expect makes the appointment more useful.
The examination concentrates on the hands: whether the skin over the fingers can be pinched up, whether the fingertips show pits or scars, whether there is calcinosis, and how fully the hands open and close. Skin thickening is scored at several sites so that change can be measured over time rather than guessed at.
Beyond the hands: blood pressure, chest examination, and a careful history of swallowing, reflux, breathlessness and bowel habit.
Baseline tests usually include lung function with gas transfer, a high-resolution CT of the chest, and an echocardiogram — not because symptoms demand them, but because lung involvement is commonly present before it is felt, and because having a baseline makes later changes interpretable.
Living with it day to day
Several practical measures make a material difference, and they are easy to underestimate.
- Keep the whole body warm, not just the hands. The body sacrifices finger circulation to protect the core, so a warm torso keeps fingers warmer than gloves alone. Gloves before going out, not after the hands are already cold.
- Protect the fingertips. Small cuts and burns heal slowly and can become ulcers. Take care with knives, hot vessels and nail cutting.
- Stop smoking. Nothing constricts small vessels more reliably, and in a disease defined by small-vessel damage this matters more than usual.
- Reflux measures. Eat earlier, raise the head of the bed rather than piling up pillows, and take acid suppression regularly if prescribed rather than only on bad days.
- Skin care. Heavy emollients on the hands, and oil before bathing rather than after.
- Know the emergency. A sudden rise in blood pressure with headache or reduced urine output needs assessment the same day.
What to do
If you have Raynaud's and any of: puffy fingers, new persistent reflux, fingertip ulcers, skin tightening, breathlessness, or a positive ANA — ask for a rheumatology assessment with nailfold capillaroscopy.
If you have ordinary Raynaud's alone, beginning in your teens, with normal hands and no other features, the odds strongly favour that it stays that way. Keep warm, protect the hands, and mention it if anything else appears.
If the combination applies to you, you can request a callback or book a consultation. Systemic sclerosis sets out the condition in full.
Common questions
What are the first signs of scleroderma?
Usually Raynaud's phenomenon — fingers changing colour in the cold — together with puffy, stiff fingers in the morning and new persistent reflux. Visible skin tightening comes later. Each sign alone is common; it is the combination that matters.
Does Raynaud's mean I will get scleroderma?
Usually not. Most Raynaud's, particularly when it starts in the teens and affects both hands equally with no other symptoms, is primary and remains so. Concern rises when it starts after about thirty, is severe, causes fingertip ulcers or scars, or comes with puffy fingers, reflux or a positive ANA.
What is nailfold capillaroscopy?
A painless examination of the tiny blood vessels at the base of the fingernail under magnification. They look normal in primary Raynaud's and are enlarged, distorted or missing in scleroderma and related conditions. It takes a few minutes and is one of the most useful tests for telling the two apart.
Why does scleroderma cause acid reflux?
The muscle of the lower oesophagus is affected early, so it does not close properly and empties slowly. Reflux that is new in an adult, persistent, worse lying flat, or accompanied by food sticking in the chest is worth mentioning alongside any hand symptoms.
Is scleroderma curable?
No, but a great deal of the damage can be prevented or slowed. Lung fibrosis is treatable and responds better before extensive scarring, pulmonary hypertension is screened for with echocardiograms, and renal crisis is a treatable emergency when recognised. Early diagnosis is what makes that monitoring possible.
What are the white chalky lumps under the skin?
Calcinosis — deposits of calcium that form under the skin, often at the fingertips or elbows. They can be painful and sometimes break through the skin and discharge a white material. They are a recognised feature of scleroderma and worth showing to your doctor.
