Overview of thumb arthritis

It's common for arthritis (osteoarthritis) to affect your thumbs. Depending on how bad it is, this can make it hard to do everyday tasks such as opening jars and doors, doing crafts and hobbies or working in the garden. It often gets worse over time.

Osteoarthritis often happens in both thumbs but one thumb is likely to be worse than the other.

You're more at risk of arthritis of the thumb is you're over 40, have had a previous injury to the area or your job involves repetitive movement of your thumb. It's also more common in women than men.
