I don't know specifically about your type of pain, but my mil said this one helped her:

If the pain is being caused by inflammation of the carpal tunnel, the heavy duty hand braces you can buy at Walmart help. My mil wears them at night. These are the ones that have the metal insert on the palm side. They keep the wrist immobilized in a neutral position while you sleep, which allows the inflammation to die down. (Have to be used for a week or more before you start noticing the relief.)
