Although more than 100 forms of arthritis exist, three types account for most of the day-to-day struggles people describe.
1. Osteoarthritis (OA)
The most common type, caused by gradual cartilage wear.
Typical symptoms include a deep joint ache, morning stiffness, swelling through the day, and difficulty with basic movements such as climbing stairs or standing up. Many describe a “grinding” or “bone-on-bone” sensation.
2. Rheumatoid Arthritis (RA)
An autoimmune condition that can cause sudden, intense flare-ups.
Symptoms often include hot, swollen joints, severe morning stiffness, fatigue, and pain that may shift between joints. RA frequently affects both sides of the body, making daily tasks difficult.
3. Post-Injury or Overuse Arthritis
Develops after sports injuries, accidents, or repetitive strain.
Even years later, the affected joint may become painful, swollen after light activity, or feel unstable and stiff.
Across all types, people often face the same challenges: disrupted sleep, limited mobility, reduced independence, and a constant sense of frustration. Arthritis affects far more than the joints—it affects everyday life.
