I don't want to sound cruel, however are you sure that you are in the right forum. There is a pain management forum. Do you have fibromyalgia. If so then I apologize and realize you are in the right forum.
I have read a lot about wrist pain - as i also have it. It is associated with many many different related disorders - i would look into any disorder associated with inflammation or swelling - perhaps, fibro, lupus, thyroid, etc. Just a thought - good luck!
