The most common cause of wrist pain is carpal tunnel syndrome, which occurs when the median nerve gets compressed at the wrist because of swelling. This usually happens when you do repetitive movements with your wrist, such as typing on a computer keyboard, using a computer mouse, sewing, painting, writing, or using a vibrating tool. Arthritis (osteoarthritis and rheumatoid) is another common cause of pain, swelling, and stiffness.
Treatment for pain includes wearing a wrist brace or splint to reduce swelling and ease the pain, applying hot or cold compresses, and taking anti-inflammatory drugs. In more severe cases, surgery may be required.
