My thumb hurts when I pinch objects or turn doorknobs. What is the problem?
There may be more than one problem, but pain at the base of the thumb (also known as the carpometacarpal or CMC joint) may indicate arthritis.

The thumb experiences subluxation (falls out of the joint) at the base and causes discomfort with daily tasks such as gripping objects, turning a doorknob or key, fastening small buttons on clothing and opening jars. Avoid pinching with your thumb on top of the index finger (similar to holding a key). Instead, try to pinch by touching your thumb to the index and little fingers.
