Why Does Your Thumb Hurt? Discover Common Causes of Thumb Pain!
Published: Jun 25, 2024
Thumb pain can be more than just a nuisance; it could be a sign of a bigger problem. Let's dive into some common causes and what they mean for you.
The Anatomy of Your Thumb
Your thumb is unique, with only two bones compared to the three in other fingers, allowing for a wide range of motion. This special structure makes it essential for gripping and pinching but also more prone to injury. Nine muscles control its movement, highlighting its complexity. Understanding this anatomy is crucial when diagnosing the causes of thumb pain.
Injuries That Cause Thumb Pain
Injuries like sprains, fractures, and dislocations are common culprits of thumb pain. For example, a skier’s thumb happens when the thumb is bent too far backward, damaging the ulnar collateral ligament. Fractures can occur from direct blows or falls, while dislocations often result from hyperextension. These injuries require careful examination and sometimes imaging to diagnose accurately.
Nontraumatic Causes of Thumb Pain
Not all thumb pain comes from injuries; conditions like arthritis and carpal tunnel syndrome can be to blame. Arthritis often leads to chronic pain at the base of the thumb, especially during activities like turning a key. Carpal tunnel syndrome can cause pain and tingling, extending to the thumb. These conditions typically develop over time and need a different treatment approach.
