Rheumatoid arthritis (RA) is a chronic autoimmune disease where the immune system attacks the joints, causing inflammation, pain, and swelling. This inflammation can lead to joint damage, deformity, and loss of function over time. RA can also affect other body systems. While the exact cause is unknown, treatments aim to manage symptoms and improve quality of life.
Common problems associated with arthritic hands include:
1. Pain and Stiffness: Persistent pain and stiffness in the joints, particularly in the fingers and knuckles, making movement difficult.
2. Reduced Grip Strength: Weakened grip strength, which makes it challenging to hold and manipulate objects securely.
3. Swelling and Inflammation: Swelling in the joints, leading to discomfort and limited range of motion.
4. Limited Dexterity: Difficulty in performing tasks that require fine motor skills, such as buttoning clothes, writing, or using utensils.
5. Joint Deformity: In advanced cases, joint deformities can develop, further limiting hand function and causing discomfort.
6. Fatigue: Increased fatigue in the hands, making it hard to sustain activities over time.
7. Loss of Range of Motion: Decreased flexibility in the fingers, leading to difficulty in fully opening or closing the hand.
8. Difficulty with Daily Tasks: Challenges in performing everyday tasks like opening jars, gripping tools, or using electronic devices.
