Rheumatoid arthritis often begins in the small joints of the fingers and wrists, and along with pain and swelling come morning stiffness and fatigue. Below: how to distinguish this condition from ordinary joint wear and why early diagnosis matters.
What It Is: Immunity Against Your Own Joints
Rheumatoid arthritis is an autoimmune disease. The immune system, which normally protects against infections, mistakenly attacks the lining of the joints. The joint swells, becomes stiff and painful, and over time inflammation damages the joint, cartilage, and adjacent bone. It primarily affects small joints—of the hands, feet, and wrists; the course is chronic, with flare-ups and remissions. Prevalence is about 0.5–1%, women are affected about three times more often, and the peak onset is at 30–35 years. Risk is higher with a family history of the disease and in smokers. For women, prolonged breastfeeding—24 months or longer—is associated with a twofold lower risk. The causes are not fully understood; hypothetical triggers include viruses (herpes, hepatitis B, mumps) and triggering factors such as hypothermia, intoxications, and stress. Without adequate treatment, inflammation can lead to ankylosis—immobility of the joint.
Early Signs: What to Look For
Joint involvement is usually symmetrical: if a joint on the right hand hurts, the same joint on the left is likely involved. Morning stiffness is one of the main signs, and the longer it lasts, the more active the disease. It is accompanied by fatigue, general weakness, low-grade fever, pain after prolonged sitting, and dry eyes and mouth. There may be myalgias, loss of appetite, and cold or sweaty palms and soles.
How It Differs from Ordinary Joint Wear
Arthritis differs from wear primarily by mechanism—autoimmune inflammation rather than cartilage wear. It is typically characterized by multiplicity and symmetry, prolonged morning stiffness, and general symptoms outside the joints. X-rays in the early stage show only soft tissue swelling: joint changes appear no earlier than six months later. Then come periarticular osteoporosis, joint space narrowing, and erosions. Bone outgrowths and osteophytes are characteristic of late-stage osteoarthritis and are usually absent in arthritis.
Extra-articular Manifestations
The disease is not limited to the joints. There may be problems in other parts of the body, as well as fatigue and weight loss. Complications include carpal tunnel syndrome, inflammation of the lungs, heart, and eyes, and an increased risk of heart attack and stroke; some of these can be life-threatening. Anemia and depression are also common.
How It Is Diagnosed
Prompt diagnosis makes sense because early treatment can slow progression and reduce the risk of joint damage. Diagnosis includes blood tests and X-rays. A complete blood count shows inflammatory changes and anemia, and ESR assesses disease activity. Serological testing looks for rheumatoid factor, and biochemistry—for changes in proteins and iron. X-rays are taken of the hands, feet, wrist and knee joints, and cervical spine. The decision about treatment is made by a doctor.
What to Bring to the Doctor
A planned conversation with a family doctor is not about a single morning stiffness but about the picture: when it started, which joints are involved, how long stiffness lasts, and what else has changed.
Call 103 or 112 immediately if there is a threat to life—including signs of stroke or heart attack.
Questions for the doctor at the appointment:
- When did the stiffness start and how many minutes does it last now?
- Is the involvement symmetrical and which joints are affected?
- Which tests are needed first—blood tests, X-rays?
- What to do if the X-ray shows no changes yet?
