It could be inflamed: You may want to see a doctor it could be inflammation of the joint. You should see your doctor. Ice and Ibuprofen will help.

Arthritis: If a person has arthritis or instability at the joint at the base of the thumb (basilar joint) the muscles hurt or spasm to protect the joint. It can occur on either hand or both.
