Rheumatoid arthritis (RA) causes chronic, symmetrical joint pain, stiffness, and swelling due to immune system attacks on joint linings. Unlike wear-and-tear osteoarthritis, RA often feels worse with movement and improves with rest.
RA pain typically starts in smaller joints like fingers and toes, spreading symmetrically (both hands, both knees). The pain feels deep, achy, and burning, often accompanied by morning stiffness lasting hours. A 2021 study in Arthritis & Rheumatology found 75% of RA patients reported stiffness lasting over an hour.
Unlike osteoarthritis, which worsens with use, RA pain often spikes during flares-periods of intense inflammation. Flares may cause joints to feel warm, tender, and swollen, sometimes with redness. Some patients describe a "grinding" sensation when moving affected joints.
RA is often mistaken for fibromyalgia, lupus, or gout. Unlike RA, gout causes sudden, severe pain (often in one joint) and may involve visible lumps. Fibromyalgia causes widespread pain without swelling. RA is also frequently confused with viral infections like influenza, as both can cause fatigue and muscle aches.
I interviewed Sarah, a 38-year-old RA patient who described her daily routine: "Morning stiffness keeps me from making breakfast. By afternoon, my hands feel like they're on fire. Even simple tasks like turning a doorknob can trigger sharp pain." She uses heat packs for stiffness and ice for flares.
Consult a doctor if joint pain lasts over six weeks, occurs symmetrically, or includes unexplained fatigue. Early treatment with disease-modifying drugs can prevent joint damage. RA blood tests look for rheumatoid factor or anti-CCP antibodies, though 10-15% of patients test negative.
