Your thumb is likely swelling due to either osteoarthritis or reactive arthritis.
Common Causes of Thumb Swelling
| Cause | Description |
|---|---|
| Osteoarthritis | The most common cause, it's the age-related breakdown of joint tissue, especially at the thumb's basal joint. |
| Reactive Arthritis | Triggered by an infection elsewhere in the body. |
Understanding Osteoarthritis and Thumb Swelling
- Age-Related: Osteoarthritis is often associated with aging, which leads to wear and tear on the joints.
- Basal Joint: The basal joint, located at the base of the thumb, is particularly susceptible to osteoarthritis.
- Joint Tissue Breakdown: This breakdown results in swelling, pain, and limited movement.
Reactive Arthritis as a Cause
- Infection Trigger: Reactive arthritis occurs when an infection in another part of the body (e.g., urinary tract, intestines) triggers inflammation in your joints.
- Systemic Response: This is a systemic response where the body’s immune system mistakenly attacks the joints.
What to Do
- Consult a Doctor: See a healthcare professional for proper diagnosis and treatment.
- Treatment Options: Treatments can range from pain management and physical therapy to more advanced interventions if needed.
