Lupus symptoms can vary widely. Some people have mild symptoms that come and go. Others experience more severe symptoms that affect multiple organs.
If you are wondering whether your symptoms could be lupus, it’s important to understand what to look for and when to seek care.
Early lupus symptoms are often vague and can mimic other conditions. Many people first notice:
Because these symptoms overlap with many other conditions, lupus can be difficult to recognize at first.
Lupus is an autoimmune disease, meaning the immune system attacks healthy tissues. It can affect the skin, joints, kidneys, heart, lungs and brain.
Severe, persistent tiredness is one of the most common symptoms. It can interfere with work, school and daily activities.
Pain, stiffness and swelling often occur in the fingers, hands, wrists and knees. Unlike rheumatoid arthritis, lupus joint damage is usually less destructive.
The most well-known rash is the malar (butterfly) rash, which appears across the cheeks and nose. It may worsen with sun exposure.
Other skin symptoms may include:
A low-grade fever above 100.4°F may occur during flares.
Swelling may develop in the legs, feet or around the eyes, especially if the kidneys are involved.
Lupus is a systemic disease, meaning it can affect many parts of the body.
Lupus nephritis is a serious complication. Symptoms may include:
Lupus can cause inflammation of the heart muscle or lining (myocarditis or pericarditis), leading to chest pain. It may also affect heart valves.
Inflammation of the lung lining (pleuritis) can cause sharp chest pain that worsens with deep breathing.
Neurological symptoms may include:
Not everyone with lupus experiences all of these symptoms.
Lupus is often called “the great imitator” because its symptoms resemble many other conditions.
It may be mistaken for:
Symptoms can also appear gradually and flare unpredictably.
There is no single test that confirms lupus. Diagnosis is based on symptoms, physical exam findings and laboratory testing.
You may first see a primary care provider and then be referred to a rheumatologist.
Antinuclear antibody (ANA) test
The ANA test looks for antibodies that attack cell nuclei. A positive result suggests autoimmune activity but does not confirm lupus on its own.
Other blood tests
Checks for protein or blood in the urine, which may signal kidney involvement.
Your provider may order:
These tests help determine organ involvement and severity.
Talk to a health care provider if you have:
Early diagnosis and treatment can help reduce organ damage and improve quality of life.
If you have symptoms that may be related to lupus, schedule an appointment with a provider experienced in autoimmune conditions. A rheumatology evaluation can help determine whether lupus or another condition is causing your symptoms.
