Basal joint arthritis, also known as thumb arthritis, is the result of the wearing away of cartilage in the joint at the base of the thumb.
Common signs and symptoms might include:
- Pain that occur at the base of your thumb when you grip, grasp or pinch an object, or use your thumb to apply force.
- Decreased range of motion
- Decreased strength when pinching or grasping objects
- Enlarged or bony appearance of the joint at the base of your thumb
- Swelling, stiffness and tenderness at the base of your thumb
Try to avoid clenching your hands when you carry things, as this can aggravate symptoms. You can also try over-the-counter pain reliever or anti-inflammatory medication to relieve the pain. A splint can also provide temporary support for your thumb and wrist, limiting movement so your joints can rest. It can also help with training your joints back into the correct position.
