What are the symptoms of rheumatoid arthritis?

Rheumatoid arthritis (RA) is a chronic autoimmune disease that primarily affects your joints but can involve other organs and systems. Understanding the full spectrum of rheumatoid arthritis symptoms can help you recognize early warning signs and seek timely treatment. Below is an overview of common and less common manifestations, based on the 2010 ACR/EULAR classification criteria and insights into disease mechanisms.

1. Joint-related rheumatoid arthritis symptoms

RA most often targets small joints first (hands, wrists, feet) and usually affects both sides of the body symmetrically. Key joint symptoms include:

• Pain and tenderness
  • Aching or sharp pain in affected joints
  • Pain worsens with movement or pressure
• Swelling
  • Soft, spongy swelling of the joint capsule (synovitis)
  • May be more noticeable in the mornings
• Morning stiffness
  • Lasts at least 30–60 minutes (classic RA feature)
  • Improves gradually with activity
• Reduced range of motion
  • Difficulty fully bending or straightening joints
  • Feels “locked” or “tight”
• Joint warmth and redness
  • Inflamed joints may feel warm to the touch
  • Overlying skin can look pink or red
• Progressive deformities (if untreated)
  • Ulnar drift (fingers angle toward the little finger)
  • Boutonnière and swan-neck deformities in the fingers
  • “Hammer” toes in the feet

2. Systemic and constitutional symptoms

RA is more than “just sore joints.” It often triggers whole-body effects due to chronic inflammation:

• Fatigue and malaise
  • Persistent tiredness not relieved by rest
  • Feelings of exhaustion or “heaviness”
• Low-grade fever
  • Mild (up to 100°F/38°C) and often intermittent
• Loss of appetite and weight loss
  • Unintended weight loss
  • Reduced interest in eating
• Generalized weakness
  • Difficulty performing daily tasks
  • Muscle aches (myalgia)

3. Extra-articular (beyond the joints) manifestations

Rheumatoid arthritis can affect skin, eyes, lungs, heart and blood vessels. These symptoms are less common but important:

• Rheumatoid nodules
  • Firm, painless lumps under the skin, often on elbows, forearms or heels
  • Occur in about 20–30% of patients
• Eye problems
  • Dry eyes, gritty sensation (keratoconjunctivitis sicca)
  • Inflammation of the white of the eye (scleritis or episcleritis)
• Lung involvement
  • Shortness of breath or chest pain (pleuritis)
  • Lung nodules or fibrosis in advanced cases
• Cardiovascular issues
  • Increased risk of heart attack, stroke, pericarditis
  • Chronic inflammation damages blood vessel linings
• Blood abnormalities
  • Anemia of chronic disease (low red blood cell count)
  • Elevated platelet count (thrombocytosis)
• Nervous system
  • Carpal tunnel syndrome (median nerve compression at the wrist)
  • Rarely, peripheral neuropathy or cervical spine instability

4. Laboratory and imaging clues

Although symptoms guide initial suspicion, tests confirm RA:

• Serologic markers
  • Rheumatoid factor (RF): positive in ~70–80% of RA patients
  • Anti–citrullinated protein antibodies (anti-CCP): more specific, positive early
• Inflammatory markers
  • Elevated erythrocyte sedimentation rate (ESR)
  • Elevated C-reactive protein (CRP)
• Joint imaging
  • X-rays: early soft-tissue swelling, later joint space narrowing and erosions
  • Ultrasound or MRI: detect synovitis and bone erosions sooner

5. How RA develops (pathogenesis overview)

According to McInnes and Schett (2011), rheumatoid arthritis arises when your immune system attacks your own joint lining (synovium):

• Immune cells (T cells, B cells, macrophages) infiltrate the synovium
• Cytokines (TNF-α, IL-6, IL-1) drive inflammation and joint damage
• Osteoclast activation leads to bone erosion and cartilage breakdown
• Genetic and environmental factors (smoking, infections) increase risk

6. When to suspect RA and next steps

If you notice persistent joint pain plus any combination of the symptoms above for more than six weeks, consider seeking medical evaluation. Early treatment can slow disease progression and reduce joint damage.

7. Tips for living with RA

While medical treatment (DMARDs, biologics, steroids) is essential, lifestyle measures can ease symptoms:

• Regular low-impact exercise (swimming, walking, yoga)
• Balanced diet rich in omega-3 fatty acids (fish, flaxseed) and antioxidants
• Joint protection techniques (assistive devices, ergonomic tools)
• Stress management (meditation, counseling)
• Adequate rest to combat fatigue

8. When to speak to a doctor

Some signs mean you need prompt medical attention:

• Sudden, severe joint pain or swelling
• High fever (>101.5°F/38.6°C) with joints red and hot
• Difficulty breathing or chest pain
• Rapid weight loss or extreme fatigue
• Signs of infection (wound redness, warmth, pus)

If you experience any life-threatening or serious symptoms, please speak to a doctor right away or go to the nearest emergency department.

Rheumatoid arthritis symptoms vary widely from person to person. Recognizing the pattern of joint pain, morning stiffness, systemic fatigue, and possible extra-articular signs is the first step toward diagnosis. Early evaluation and treatment can help you maintain quality of life and protect your joints from long-term damage.
