The painful joint between the thumb and hand is most commonly associated with basal joint arthritis, also known as osteoarthritis of the thumb. This condition affects the joint at the base of the thumb, where it connects to the hand.
Understanding Basal Joint Arthritis
Basal joint arthritis is a common form of hand arthritis, frequently affecting the thumb's base. The condition causes pain, swelling, and stiffness in the joint. Symptoms can range from mild discomfort during activity to severe pain even at rest, as the condition progresses. [Source: Mayo Clinic, HSS, Yale Medicine]
- Early Stages: Pain and stiffness may only appear during or after using the thumb.
- Advanced Stages: Pain and aching can occur even when the thumb is at rest.
- Bilateral Occurrence: Basal joint arthritis often affects both hands, although symptoms might be more pronounced in one. [Source: HSS]
Other Potential Causes of Thumb Pain
While basal joint arthritis is a frequent culprit, other conditions can cause pain near the thumb:
- De Quervain's Tenosynovitis: This involves inflammation of the tendons on the thumb side of the wrist, leading to pain at the base of the thumb and in the wrist and forearm. Repetitive thumb and wrist movements often trigger it. [Source: Aurora Health Care, Cleveland Clinic, AAOS]
- Trigger Thumb: This is a condition causing the thumb to get stuck in a bent position, releasing with a snap.
- Tendonitis: Inflammation of the tendons in the thumb can also cause significant pain.
- Carpal Tunnel Syndrome: Although affecting the wrist, it can sometimes radiate pain into the thumb.
- Skier's Thumb: A specific injury to the thumb's ligaments. [Source: The Hand Society]
Seeking Medical Attention
If you experience persistent thumb pain, it's crucial to seek a medical professional's evaluation. They can accurately diagnose the underlying cause and recommend appropriate treatment, such as medication, splints, or, in severe cases, surgery. [Source: Mayo Clinic]
