Rory,

I would highly recommend that you research a Triangular fibrocartilage tear and perform the weight bearing test found at Weight Bearing Test for Wrist Pain - WRIST WIDGET TM.

If both wrists are involved, you will not understand your normal capacity. Weight bearing is based on age, height (not weight) and bone density. If you do the test and report your findings here, I will see if I can assist you in figuring out what is wrong and what to do.

Warmest Aloha,
